O-RingA General informationA.1 DescriptionO-Rings offer the designer an efficient and economicalsealing element for a wide range of static or dynamicapplications.Inexpensive production methods and its ease of use havemade the O-Ring the most widely used seal.A wide choice of elastomer materials for both standardand special applications allow the O-Ring to be used toseal practically all liquid and gaseous media.O-Rings are vulcanised in moulds and are characterisedby their circular form with annular cross section. Thedimensions of the O-Ring are defined by the insidediameter d 1 and the cross section d 2 (Figure 1).Cross sections of approx. 0.35 to 40 mm and insidediameters up to 5,000 mm and more are available.AdvantagesCompared with other sealing elements, the O-Ring hasa wide range of advantages:- Simple, one piece groove design reduces hardwareand design costs- Compact design allows smaller hardware- Easy, foolproof installation reduces risk- Applicable to a wide range of sealing problems, static,dynamic, single or double acting- Wide compound choice for compatibility with mostfluids- Ex stock availability of many sizes worldwide for easymaintenance and repair.d1d2Figure 1O-Ring dimensioningA.2 ApplicationO-Rings are used as sealing elements or as energising elementsfor hydraulic slipper seals and wipers and thuscover a large number of fields of application. There areno fields of industry where the O-Ring is not used. Froman individual seal for repairs or maintenance to a qualityassured application in aerospace, automotive or generalengineering.The O-Ring is used predominantly for staticsealing applications:- As a radial static seal, e.g. for bushings, covers, pipes,cylinders- As an axial static seal, e.g. for flanges, plates, caps.O-Rings in dynamic applications are recommended onlyfor moderate service conditions. They are limited by thespeed and the pressure against which they are to seal:- For low duty sealing of reciprocating pistons, rods,plungers, etc.- For sealing of slowly pivoting, rotating or spiral movementson shafts, spindles, rotary transmission leadthroughs,etc.7

O-RingA.3 Method of operationO-Rings are double-acting sealing elements. The initalsqueeze, which acts in a radial or axial directiondepending on the installation, gives the O-Ring its initialsealing capability. These forces are superimposed by thesystem pressure to create the total sealing force whichincreases as the systeme pressure increases (Figure 2).Under pressure, the O-Ring behaves in a similar way toa fluid with high surface tension. The pressure istransmitted uniformly to all directions.PressureFigure 2O-Ring sealing forces with and withoutsystem pressure8

O-RingB Technical informationB.1 MaterialsB.1.1 ElastomersEquipment manufacturers and end users expect sealingsystems to operate leak free and to maintain long servicelife. Reliability is crucial to effective low maintenance costoperations. To find the perfect sealing solution in eachindividual case both material performance and sealdesign are critically important. One of the main usedmaterial groups for sealings are the elastomers. Theyshow good properties like elasticity or good chemicalcompatibility.The following tables provide a summary of the variouselastomer material groups.

O-RingB.1.2 Application parameters of elastomersElastomers as all other organic chemicals have limiteduse. External influences such as various media, oxygen orozone as well as pressure and temperature will affect thematerial properties and therefore their sealing capability.Elastomers will amongst others swell, shrink or hardenand develop cracks or even tears.The following information illustrates the differentapplication parameters.Elastomer heat resistance / swelling in oilMax working temperature (°C)max. 325depends onACN content2252001751501251007500 20 40 60 80 120 140 160Change of volume in IRM-OIL 903, 70h (%)Figure 3 Change of volume in IRM-Oil 903 (old ASTM-Oil No 3)11

Details regarding resistance inspecial media are shown in chapter ”Chemicalcompatibility”, page 13.The various elastomers can be characterised as follows:NBR (Nitrile Butadiene Rubber):The properties of the Nitrile Rubber depend mainly on theACN content which ranges between 18% and 50%. Ingeneral they show good mechanical properties. Theoperating temperatures range between -30 C and+100 C (for a short period of time up to +120 C).Suitable formulated NBR can be used down to -60 C.NBR is mostly used with mineral based oils and greases.FKM (Fluorocarbon Rubber)Depending on structure and fluorine content FKMmaterials can differ with regards to their chemicalresistance and cold-flexibility.FKM is known especially for its non-flammability, low gaspermeability and excellent resistance to ozone,weathering and aging.The operating temperatures of the Fluorocarbon Rubberrange between -20 C and +200 C (for a short periodof time up to +230 C). Suitable formulated FKM can beused down to -35 C. FKM is also often used with mineralbased oils and greases at high temperatures.EPDM (Ethylene Propylene Diene Rubber)EPDM shows good heat, ozone and aging resistance. Inaddition they also exhibit high levels of elasticity, good lowtemperature behaviour as well as good insulatingproperties.The operating temperatures of applications for EPDMrange between -45 C and +150 C (for a short periodof time up to +175 C). With sulphur cured types therange is reduced to -45 C and +120 C (for short periodof time up to +150 C).EPDM can often be found in applications with brake fluids(based on glycol) and hot water.12

O-RingHNBR (Hydrogenated Nitrile Butadiene Rubber)HNBR is made via selective hydrogenation of the NBRbutadiene groups. The properties of the HNBR rubberdepend on the ACN content which ranges between 18%and 50% as well as on the degree of saturation. HNBRshows good mechanical properties.The operating temperature of HNBR ranges between-30 C and +140 C (for a short period of time up to+160 C) in contact with mineral oils and greases.Special types can be used down to -40 C.Q (Silicone Rubber)Silicone rubber shows excellent heat resistance, coldflexibility, dielectric properties and especially goodresistance against oxygen and ozone.Depending on the material the operating temperaturesranges between -60 C and +200 C (for a short periodof time even up to +230 C). Special types can be useddown to -90 C. There are also some types with narrowtemperature ranges. Silicone is often used in the medicalandfood industry.CR (Chloroprene Rubber)In general the CR materials show relatively goodresistances to ozone, weathering, chemicals and aging.Also they show good non-flammability, good mechanicalproperties and cold flexibility.The operating temperatures range between -40 C and+100 C (for a short period of time up to +120 C).Special types can be used down to -55 C.CR materials are found in sealing applications such asrefrigerants, for outdoor applications and in the glueindustry.ACM (Polyacrylate Rubber)ACM shows excellent resistance to ozone, weatheringand hot air, although it shows only a medium physicalstrength, low elasticity and a relatively limited lowtemperature capability.The operating temperatures range from -20 C and+150 C (for a short period of time up to +175 C).Special types can be used down to -35 C.ACM-materials are mainly used in automotiveapplications which require special resistance to lubricantscontaining many additives (incl. sulphur) at hightemperatures.FFKM (Perfluoro Rubber)Perfluoroelastomers show broad chemical resistancesimilar to PTFE as well as good heat resistance. They showlow swelling with almost all media.Depending on the material the operating temperaturesrange between -25 C and +240 C. Special types canbe used up to +325 C.Applications for FFKM can be mostly found in thechemical and process industries and in all applicationswith either aggressive environments or hightemperatures.Chemical compatibilityIt is important to recognise that when using this guide, theratings shown are based on published data andimmersion tests. These tests are conducted underlaboratory conditions and may not represent adequatelythe conditions in the field. Relative short term laboratorytests may not pick up all the additives and impuritieswhich may exist in long term service applications.Care must be taken to ensure that all aspects of theapplication are considered carefully before a material isselected. For example at elevated temperatures someaggressive fluids can cause a much more marked effecton an elastomer than at room temperature.Physical properties as well as fluid compatibility need tobe considered. Compression set, hardness, abrasionresistance and thermal expansion can influence thesuitability of a material for a particular application.It is recommended that users conduct their own tests toconfirm the suitability of the selected material for eachapplication.Our experienced technical staff can be consulted forfurther information on specific applications.Rating systemABCUVery good suitabilityElastomer shows little or no effect from exposure.Little effect on performance and physicalproperties.

O-RingB.1.3 Characteristics and inspection of elastomersHardnessOne of the most often named properties regardingPolymer materials is hardness. Even so the values can bequite misleading.Shore AShore DHardness is the resistance of a body against penetrationof an even harder body – of a standard shape definedpressure.There are two procedures for hardness tests regardingtest samples and finished parts made out of elastomermaterial:1. Shore A/Daccording to ISO 48 / DIN 53 505 / ASTM D 2240Measurement for test samples2. Durometer IRHD (International Rubber HardnessDegree) according to ISO 48 / DIN 53 519-1 and -2 /ASTM 1414 and 1415Measurement of test samples and finished partsThe hardness scale has a range of 0 (softest) to 100(hardest). The measured values depend on the elasticqualities of the elastomers, especially on the tensilestrength.The test should be carried out at temperatures of 23 2 C– not earlier than 16 hours after the last vulcanisationprocess (manufacturing stage). If other temperatures arebeing used this should be mentioned in the test report.Tests should only be carried out with samples which havenot been previously stressed mechanically.Hardness tests according to Shore A / DThe hardness test device Shore A (indentor with pyramidbase) is a sensible application in the hardness range 10to 90. Samples with a larger hardness should be testedwith the device Shore D (indentor with spike).Test specimen:Diameter min. 30 mmThickness min. 6 mmUpper and lower sides smoth and flatWhen thin material is being tested it can be layeredproviding minimal sample thickness is achieved by amaximum of 3 layers. All layers must be at minimum2 mm thick.The measurement is done at three different places at adefinded distance and time.Figure 51.25 + 0.15 mm 1.25 + 0.15 mm0.79 + 0.01 mmIndentor according to Shore A / DHardness test according to IRHDThe test of the Durometer according to IRHD is used withtest samples as well as with finished goods.The thickness of the test material has to be adjustedaccording to the range of hardness. According toDIN 53 519-1 there are two hardness ranges.Soft:10 to 35 IRHD Sample thickness greaterthan 10 to 12 mmNormal: over 35 IRHD Sample thickness6 to 10 mmSample thickness1.5 to 2.5 mm / measuredaccording to DIN 53 519-2The hardness determined with finished parts or samplesusally vary in hardness determined from specimensamples, especially those with a curved surface.Soft,DIN 53519-1Figure 65 mmVertically carried poleNormal,DIN 53519-12.5 mmIndentor according to IRHDNormal,DIN 53519-20.4mm30

O-RingInfluencing parameters on the hardness test forpolymer materialsVarious sample thicknesses and geometries as well asvarious tests can show different hardness values eventhough the same materials have been used.O-Ring, NBR 75 Shore AHardness777573716967656361With equivalent material characteristics of the elastomersample B, the indentor penetrates the deepest at thesurface 3 (concave) and therefore establishes the softestarea.As the concave geometry (3) has a stronger effect onsmaller width O-Rings, the tolerances on hardness forwidths under 2.5 mm should be increased up to+5 / -8 IRHD.Compression setAn important parameter regarding the sealing capabilityis the compression set (CS) of the O-Ring material.Elastomers when under compression show aside from anelastic element also a permanent plastic deformation(Figure 9).The compression set is determined in accordance withDIN 53517 as follows:Standard test piece: Cylindrical disc, diameter 13 mmand height 6 mmDeformation: 25%Tension release time: 30 minutes5957550 1 1.5 2 2.5 3.5 5 6 7Thickness of test-buttons [mm]Shore A IRDH, DIN 53 519-1 IRDH, DIN 53 519-2Where h 0 = Original height (cross section d 2 )h 1 = Height in the compressed stateh 2 = Height after tension releaseFigure 7Ranges of hardness depending on samplethickness and test methodh 0A A Ah1h2h3h 11convex2plainh1 < h2 < h33concaveh 2Figure 8Range of hardness depending on surfacegeometry for the equivalent materialcharacteristics.Figure 9Illustration of the compression set31

O-RingThe accuracy of the measured value depends on: Test sample thickness Deformation Measurement deviationsTherefore the values which have been identified with thetest sample cannot be transferred onto the finished part.The result of the measured finished parts are strongly influencedby geometrics and measurements as well as themeasuring accuracy of the test equipment.The following illustration shows the influence of variousmeasuring deviations (in mm) in respect to the establishedcompression set CS depending on the cross sectionof the measured O-Rings.Resulting measuringdeviations CS (in %)76 1.00 1.78 2.6254321 4.00 5.33 6.99 10.0000 0.005 0.010 0.015 0.020 0.025Measuring deviations of measuring devices absolute (in mm)Figure 10Measuring deviations CS depending on O-Ring cross section and measuring accuracy of the test equipment(schematic illustration)32

Please use the Isolast brochure or contact our specialists for further details.B.2.1 Installation recommendationscorrectwith lead-inchamferGeneral recommendationsBefore starting installation, check the following points:- Lead-in chamfers made according to drawing?- Bores deburred and edges rounded?- Machining residues, e.g. chips, dirt and foreignparticles, removed?- Screw thread tips covered?- Seals and components greased or oiled?Ensure media compatibility with the elastomermaterial. B+S recommends to use the fluid to besealed.- Do not use lubricants with solid additives, e.g.molybdenum disulphide or zinc sulphide.Figure 12incorrectwithout lead-inchamferPiston installation with O-Ringcorrectwith lead-inchamfercorrectwithlead-inchamferincorrectwithout lead-inchamferFigure 11Rod installation with O-Ringincorrectwithoutlead-inchamferFigure 13Manual installationO-Ring installation over transverse bores- Use tools without sharp edges!- Ensure that the O-Ring is not twisted, use installationaids to assist correct positioning- Use installation aids wherever possible- Do not over stretch O-Rings- Do not stretch O-Rings made out of cord at the joint.38

O-RingInstallation over threads, splines etc.Should the O-Ring have to be stretched over threads,splines, keyways etc., then an assembly mandrel isessential. This mandrel can either be manufactured in asoft metal or a plastic material obviously without burrs orsharp edges.Automatic installationAutomatic O-Ring installation requires goodpreparation. The surfaces of the O-Rings are frequentlytreated by several methods (see chapter ”O-Ring frictionreduced”). This offers a number of benefits duringinstallation by- Reducing the installation forces- Non-stick effects, easy removalThe handling and installation of dimensionally unstablecomponents requires a great deal of experience. Reliableautomated installation thus demands special handlingand packing of the O-Rings.Please ask our specialists for further details.Pressure = 0Pressure > 0Initial squeezeB.2.2 Initial compressionAn initial compression (squeeze) of the O-Ring in thegroove is essential to ensure its function as a primary orsecondary sealing element (Figure 14). It serves to:- Achieve the initial sealing capability- Bridge production tolerances- Assure defined frictional forces- Compensate for the compression set- Compensate for wearDepending on the application, the following values applyfor the initial squeeze as a proportion of the cross section(d 2 ):Dynamic applications: 6 to 20%Static applications: 15 to 30%The design of the grooves can be based on the guidevalues for the initial squeeze shown in the diagrams inFigure 15a/b. These take into account the relationshipbetween loads and cross sections according toISO 3601-2.Figure 14Initial squeeze in %Initial squeeze in %302520151050302520151050O-Ring contact pressure installed and underservice pressureHydraulics, dynamic1.8 2.65 3.55 5.3 7O-Ring cross section d2 in mmPneumatics, dynamic1.8 2.65 3.55 5.3 7O-Ring cross section d2 in mmmax.min.max.min.Figure 15a Permissible range of Initial squeeze as afunction of cross section39

Maximum elongation inthe installed state is 6% for O-Rings with an innerdiameter > 50 mm and 8% for O-Rings with an innerdiameter < 50 mm.With external grooves - ”inside sealing” - the O-Ring ispreferably compressed along its circumference. Themaximum circumferential compression in the installedstate is 3%.Exceeding these values will result in too large increase ordecrease in the O-Ring cross section. Consequently thiscan effect the service life of the seal.The reduction in cross section diameter (d 2 ) can becalculated aswithd 1min = minimum inside diameter of the O-Ringd 2min = minimum cross section of the O-Ringd 3max = maximum housing diameterbut for approximation it can be assumed, in percentage,to be half the amount of stretch. An elongation of 1%corresponds to a reduction of the cross section (d 2 ) ofapprox. 0.5%.40

O-RingB.2.4 Methods of installation and design of seal housingMethods of installationO-Rings can be used in components in a wide variety ofways.During the design stage installation must be taken intoconsideration. In order to avoid damage duringinstallation it should not be necessary to pass the O-Ringover edges or bores. When long sliding movements areinvolved, the seal seat should be recessed, if possible, orthe O-Rings arranged so that they only have to travel shortdistances during installation to reduce risk of twisting.Radial installation (static and dynamic)Inner sealingThe O-Ring size should be selected so that the insidediameter d 1 has the smallest possible deviation from thediameter to be sealed d5 (Figure 17).Outer sealing.The O-Ring size should be selected so that the insidediameter d 1 is equal to or smaller than groove diameterd 3 (Figure 17).Axial installation, (static)During axial-static installation, the direction of thepressure should be taken into consideration whenchoosing the O-Ring size (Figure 18). With internalpressure the O-Ring should be chosen so that the outsidediameter of the O-Ring is approx. 1 to 2% larger than theouter groove diameter d7. With external pressure theO-Ring is chosen approx. 1 to 3% smaller than the innergroove diameter d8.d1d3d2d5Figure 17Radial installation, static and dynamicd8d7d8d7pressure from insidepressure from outsideFigure 18Axial installation, static41

O-RingO-Ring as a rotary sealIn some applications, e.g. with short running periods, theO-Ring can also be used as a rotary seal for sealingshafts. In this case, the following points should beobserved:In order to be able to function as a rotary seal, O-Ringsmust be installed in accordance with specific guidelines,the rotary seal principle.The rotary seal principle is based on the fact that anelongated elastomer ring contracts when heated (Jouleeffect). With the normal design criteria the O-Ring insidediameter d 1 will be slightly smaller than the shaftdiameter, and the heat generated by friction would causethe ring to contract even more. This results in a higherpressure on the rotating shaft so that a lubricating film isprevented from forming under the seal and even higherfriction occurs. The result would be increased wear anda premature failure of the seal.Using the rotary seal principle, this is prevented by theseal ring being selected so that its inside diameter isapproximately 2 to 5% larger than the shaft diameter tobe sealed. The installation in the groove means that theseal ring is compressed radially and is pressed againstthe shaft by the groove diameter. The seal ring is thusslightly corrugated in the groove, a fact which helps toimprove the lubrication.The rotary seal principle can be neglected at peripheralspeeds of less than 0.5 m/s.Special materials are available for rotary sealapplications. B+S does not recommend the use ofO-Rings as rotary seals. Please contact your local B+Scompany for further details.Technical dataO-Rings can be used in a wide range of applications.Temperature, pressure and media determine the choiceof appropriate materials. In order to be able to assess thesuitability of the O-Ring as a sealing element for a givenapplication, the interaction of all the operatingparameters have to be taken into consideration.Working PressureStatic application- up to 5 MPa for O-Rings with inside diameter > 50 mmwithout Back-up Ringup to 10 MPa for O-Rings with inside diameter< 50 mm without Back-up Ring(depends on the material, the cross section and theclearance)- up to 40 MPa with Back-up Ring- up to 250 MPa with special Back-up RingPlease note the permissible extrusion gaps.Dynamic application- Reciprocating up to 5 MPa without Back-up Ring- Higher pressures with Back-up RingSpeedReciprocating up to 0.5 m/sRotating up to 2.0 m/sDepending on material and application.TemperatureFrom -60 C to +325 CDepending on material and media resistance.When assessing the application criteria, the peak andcontinuous operating temperature and the runningperiod must be taken into consideration. For rotatingapplications the temperature increase due to frictionalheat must be taken into account.MediaWith the wide range of the available materials, each withdifferent properties, it is possible to seal againstpractically all liquids, gases and chemicals. Please notewhen selecting the most suitable material the informationin chapter “B.1 Materials” and in our O-Ring MaterialGuide.42

The table is valid for elastomericmaterials with the exception of polyurethane and FEPencapsulated O-Rings.For pressure above 5 MPa for O-Rings with Insidediameter > 50 mm and above 10 MPa for O-Rings withInside diameter < 50 mm we recommend the use ofBack-up Rings.43

If this is not the case, the clearance should bekept correspondingly smaller.For static applications we recommend a fit of H8/g7.O-Rings made from polyurethane can bridge largerclearances thanks to their high extrusion resistance andgreater dimensional stability. See also chapter”Polyurethane O-Rings”.SurfacesUnder pressure, elastomers adapt to irregular surfaces.For gas or liquid tight joints, however, certain minimumdemands must be made on the surface quality of the surfacesto be sealed.Fundamentally grooves, scratches, pit marks, concentricor spiral machining scores, etc. are not permissible.Higher demands must be placed on dynamic mating surfacesthan on static surfaces.At present no uniform definitions exist for describing themating surfaces. In practice, the specification of the R avalue is not sufficient to permit an assessment of the surfacequality.

O-RingC.2 Tolerances of dimensionsDuring vulcanisation, elastomers are subject todimensional changes due to shrinkage. The degree ofshrinkage depends on material, mould geometry and onthe vulcanisation process employed.The following tables XVIII and XIX show the tolerances forthe inside diameter (d 1 ) and cross section (d 2 ). The tablesare valid for all 70 Shore A Nitrile (NBR) elastomermaterials; other materials may exhibit differentdimensional tolerances if they are produced from mouldsdesigned for NBR 70 materials. To guarantee a high andconstant quality level it might be necessary to producenew or additional moulds with the corresponding costs.Precision O-Rings with reduced tolerances are availableif required - please contact your local B+S company.O-Ring dimensions not included in the tables aremanufactured acc. to tolerances based on ISO 3601.Table XVIIICross section tolerances based onISO 3601-1Cross sectiond2Tolerances± 1.80 0.081.80 < d 2 2.65 0.092.65 < d 2 3.55 0.103.55 < d 2 5.30 0.135.30 < d 2 7.00 0.157.00 < d 2 8.00 0.188.00 < d 2 10.00 0.2110.00 < d 2 12.00 0.25d 2 > 12.00 on requestTable XIX Tolerances for O-Ring inside diameters d 1 based on ISO 3601-1Inside diameterTolerancesd 1 ±d 1 2.50 0.132.50 < d 1 4.50 0.144.50 < d 1 6.30 0.156.30 < d 1 8.50 0.168.50 < d 1 10.00 0.1710.00 < d 1 11.20 0.1811.20 < d 1 14.00 0.1914.00 < d 1 16.00 0.2016.00 < d 1 18.00 0.2118.00 < d 1 20.00 0.2220.00 < d 1 21.20 0.2321.20 < d 1 23.60 0.2423.60 < d 1 25.00 0.2525.00 < d 1 26.50 0.2626.50 < d 1 28.00 0.2828.00 < d 1 30.00 0.2930.00 < d 1 31.50 0.3131.50 < d 1 33.50 0.3233.50 < d 1 34.50 0.33Inside diameterTolerancesd 1 ±34.50 < d 1 35.50 0.3435.50 < d 1 36.50 0.3536.50 < d 1 37.50 0.3637.50 < d 1 38.70 0.3738.70 < d 1 40.00 0.3840.00 < d 1 41.20 0.3941.20 < d 1 42.50 0.4042.50 < d 1 43.70 0.4143.70 < d 1 45.00 0.4245.00 < d 1 46.20 0.4346.20 < d 1 47.50 0.4447.50 < d 1 48.70 0.4548.70 < d 1 50.00 0.4650.00 < d 1 51.50 0.4751.50 < d 1 53.00 0.4853.00 < d 1 54.50 0.5054.50 < d 1 56.00 0.5156.00 < d 1 58.00 0.5258.00 < d 1 60.00 0.54112

O-RingD Special O-RingsD.1 Isolast (FFKM) O-RingsInformation about our Isolast (FFKM) O-Rings areavailable either in our special Isolast brochure orthrough your local Busak + Shamban company.D.2 FEP encapsulated O-RingsFEP encapsulated O-Rings consist of an elastomer innerring and a seamless FEP sheath which surrounds theelastomer ring.Similar to PTFE O-Rings FEP encapsulated O-Rings areused wherever the chemical resistance of normalelastomer O-Rings are not sufficient.The required elasticity is provided by the elastomer ring,the chemical resistance by the seamless FEP sheath.Advantages- Very good chemical resistance to most liquids andchemicals, with the exception of liquid alkaline metalsand some fluorine compounds- Temperature application range from approx. -60 °C to+200 °C (depending on the material for the inner ring)- Can be used with foodstuffs, pharmaceutical andmedicinal products- Physiologically safe and can be sterilised- Low friction, no adhesion or stick-slip effect- Adequate elastic behaviour for improved sealibility.VersionsStandard versions: Elastomer O-Ring with FEP sheathSpecial versions: Hollow elastomer ring with FEPsheathFigure 27ApplicationsFEP sheathElastomer O-RingFEP sheathHollow elastomer ringDifferent versions of FEP O-RingFields of applicationFEP encapsulated O-Rings are ideally suited for usein the chemical, petrochemicals, medical technology,foodstuffs, water, sewage and similar sectors of industry.A typical application for FEP encapsulated O-Rings is thesealing of valve spindles and as secondary sealingelements for mechanical seals.FEP encapsulated O-Rings are used primarily as staticseals. They are also suitable for use as sealing elementsfor slow switching and rotary movements.In the chemical process industry, seals with special sealingprofiles are frequently required. For such applications, wemanufacture special seals for various flange crosssections either from drawings or from templates (Figure28).118

O-RingInner ringA choice of two materials is available for the elastomerinner rings. The choice of the material also determines theservice temperature range.- Fluoroelastomer (FKM), material code VZ00Rtemperature range: - 20 C up to + 200 C- Silicone elastomer (VMQ), material code SZ00Rtemperature range: - 60 C up to + 200 CThe specified temperature ranges are limits which mustalways be considered in conjunction with the medium tobe sealed and the working pressure. The permissiblecontinuous operating temperatures are always lowerthan the upper limits.Design recommendationsFEP encapsulated O-Rings are fully interchangeable withstandard O-Ring seals. There is no need to modifythe groove dimensions. The FEP sheath is relativelythin-walled.Figure 28Technical dataSeals for special flange cross sectionsWorking pressure: Up to 25 MPaTemperature:Media:MaterialsFEP sheath- 60 C to + 200 C - dependingon the elastomer materialPractically all liquids, gases andchemicalsFEP is the abbreviated designation for Tetrafluoroethylene-hexafluoropropylene.This material has similarproperties to those of Polytetrafluoroethylene (PTFE). Italso has a very high chemical resistance and exhibits agood resistance to abrasion.In contrast to PTFE, however, FEP is thermoplasticallymouldable. This allows the material to be processed toform flexible semifinished products, such as thin-walledhoses.All the specifications given in this catalogue thereforerefer to the installation dimensions of elastomer O-Rings.As a result of the FEP sheath, the O-Rings are less flexiblethan elastomer O-Rings. They have limited stretch andhigher permanent deformation.Split grooves are recommended, especially for outsidesealing FEP encapsulated O-Rings, in order to avoidoverstretching during installation.The general information on the construction, design andsurfaces given for the elastomer O-Rings applies also toFEP encapsulated O-Rings.At higher pressures, additional concave Back-up Ringsshould be used.Application in gasesWhere the O-Ring is used to seal gases, the permeationrate must be taken into consideration. In this case thematerial of the inner ring must also have a goodresistance to the medium to be sealed. The permeationrate depends on the exposed surface area, thetemperature, the working pressure and the thickness ofthe FEP sheath.The thickness of the FEP sheath can be found in table XXll.119

It should be noted, however, that the O-Ringshave only limited stretch due to the FEP sheath.If, for design reasons, a split groove is not possible,auxiliary tools must be used for installation.For inside sealing applications (e.g. rod), FEPencapsulated O-Rings can be installed with largerdiameters without tools. On no account should the sealring be forced into the groove (e. g. by bending),otherwise the sealing function cannot be assured.120

O-RingD.3 PTFE O-RingsO-Rings in Polytetrafluoroethylene (PTFE) are closed,circular rings with annular cross section. The dimensionsare - as with the elastomer O-Ring - characterised by theinside diameter d 1 and the cord diameter d 2 (Figure 31).PTFE O-Rings are not moulded but produced bymachining. The rings can therefore be manufactured inall sizes.Technical dataWorking pressure: Up to 40 MPaTemperature:Media:- 200 C to + 260 CPractically all liquids, gases andchemicalsMaterialsFigure 31Advantagesd1O-Ring dimensionsd2- Very good chemical resistance, compatible with mostliquids and chemicals, with the exception of liquidalkaline metals and some fluorine compounds.- Wide temperature range from approx. - 200 C to+ 260 C- Suitable for contact with foodstuffs, pharmaceuticaland medicinal products- Physiologically safe, can be sterilised- Low friction, no adhesion- Available for all diameters up to approx. 1,000 mm.Standard material: Virgin, unfilled PTFE(polytetrafluoroethylene), Material Code PT00PTFE is a partially crystalline thermoplastic characterisedby a very high chemical and thermal resistance. PTFE hasthe highest resistance to chemicals of all plastics and canbe used for almost any application. It has a slightly limitedresistance to molten alkaline metals, to elementaryfluorine and to certain halogen materials.The material undergoes no changes on exposure toageing, light and ozone. The water absorption rate is lessthan 0.01 %.Design recommendationsPTFE O-Rings have low elasticity. The O-Ring size shouldtherefore be chosen to suit the nominal diameter (rod orbore) to be scaled. Installation in axial easily accessibleand radial split grooves is to be preferred.The general information on the construction, design andsurfaces given for the elastomer O-Rings applies also toPTFE O-Rings.ApplicationsFields of applicationPTFE O-Rings are used wherever the chemical andthermal resistance of the normal elastomer O-Rings is nolonger sufficient. These are primarily applications in thechemical industry, foodstuffs industry, pharmaceuticalsand medical technology. PTFE O-Rings are used only asstatic seals, e.g. on flange connections, on covers, etc.Methods of installationPTFE O-Ring can only be stretched or compressed to avery limited extent during installation.During installation, e.g. on flanges, the cold flowtendency of the thermoplastic PTFE should be taken intoconsideration. Under pressure, PTFE deforms plasticallyalso in the cold state, i.e. a permanent deformation takesplace. If flange seals are not tightened sufficiently to givemetal/metal contact, the elastic deformation and thus theelastic tension can deteriorate.122

O-RingD.4 Polyurethane O-RingsPolyurethane is becoming more and more widely used asa sealing material due to its exceptionally high abrasionresistance and high extrusion resistance.The polyurethane materials from Busak + Shambanhave a number of improved properties.Polyurethane is therefore an ideal material for O-Ringsand sealing elements.The outstanding properties of the materials play a majorrole particularly in the WU7TI, a 70 Shore A hardnessmaterial with low compression set, good hydrolysis behaviour,high flexibility, etc. see table XXVI.Polyurethane O-Rings are available in dimensions toAmerican Standard AS 568 A (see dimension list, tableXXVII, page 126-127).The dimensions are given with the inside diameter ”d 1 ”and the cord diameter”d 2 ” (Figure 35, page 126).AdvantagesThe main adavantages of a polyurethane material forO-Rings compared with other elastomer are the outstandingmechanical properties:- High abrasion and wear resistance tolerates aggressiveoperating conditions- High extrusion resistance allows increased pressuresor extrusion gaps- Good mechanical properties improve service life- Low friction reduces breakout forces on start upApplicationsFields of applicationPolyurethane O-Rings are especially suited whereverO-Rings are subject to dynamic loads.This includes for example, applications in hydraulics,pneumatics and in a wide range of other critical areas. Inmany cases, polyurethane O-Rings are used instead ofNBR in view of their high mechanical strengths.Due to their particularly high abrasion resistance,polyurethane O-Rings are more suitable than othermaterials in applications where bores have to be crossedor where frequent opening and closing is demanded, e.g.plug connectors and couplings.Polyurethane O-Rings in 70 Shore A hardness materialWU7TI can, with advance, be used in applications suchas pneumatics where low compression set and low frictionare essential.Technical dataWorking pressure: Static up to approx. 100 MPawithout Back-up Ring(depending on the extrusion gap)Dynamic up to 25 MPaSpeed:Temperature:Reciprocating up to 0.2 m/s-30 o C up to +100 o CMedia: Hydraulic fluids and mineraloil-based greases and air.MaterialsThe most important characteristics of these polyurethanesare:- High tensile strength- Low compression set- Very good cold flexibility- Constant shear modulus even at high temperatures- Resistant to weathering and ageing- High damping properties- Low gas permeability- Good hydrolysis resistance- High tear propagation resistance- Free from substances which hinder paint coverage124

O-RingD.6 O-Ring surface treatmentsIn many cases standard elastomeric O-Rings cannot beused without a modified surface. Friction can be one ofthe reasons. Also the possible contamination of thesystems through extraction of material components isoften not acceptable.Therefore O-Rings can be surface-treated by special waysof cleaning, dipping, spraying or coating in order toreduce friction and adhesion, achieve permanentlubrication or facilitate installation.Depending on the desired effect several high-qualitysurface treatments or coatings can be used. These aredescribed in the following sections.D.6.1 O-Rings free of substances causing problems with paint wetting ”Labs-free”In compressed-air processing, these Labs-free O-Ringsare particularly suited to highly-automated painttechnology, primarily in the automobile industry. Thesealing property of being ”silicon-free” is frequently nolonger adequate here.Plant must be free from all substances posing paintwetting problems.A high-technology cleaning process fulfils VW Testspecification no. 3.10.7., along with other regulations.Every batch is checked and documented accordingly. Nosubsequent exuding of the mixture components takesplace, making medicine another possible area ofapplication. The special packing in ”labs-free” bags andappropriate labeling also make storage problem-free.This absolutely environment-friendly process does notchange the physical properties of the O-Ring. In addition,these cleaned components, being dry, are very suitablefor automatic assembly. O-Rings made of FKM areespecially suitable for this treatment.Article group OC.OxygenContaminationContamination-free surfacewith excellent absorptionproperty1.Before Plasma-processand “Labs-free” cleaning2.Plasma-Process“Labs-free” cleaning(through the completecross section of the seal)3.After “Labs-free” cleaning,no contaminants remainon the surface or in thesealFigure 36Schematic course of the labs-free treatment130

The elements must be treated in such a way thatthey can be separated without problems. Depending onthe application area, stick-slip phenomena and highbreakaway forces need to be prevented. Particularly inthe transmission of dynamic functions, as in the case ofshort strokes and infrequent switch operation, or in thereduction of assembly forces, e. g. plug connections, areduction of friction is demanded.The table XXXI provides a summary of different surfacetreatments and the selection criteria.

The MoS 2 is incorporated as a drylubricating film by tumbling onto the sealing surface. Thisgives rise to mechanical interlocking, which over a longperiod, brings about a reduction in friction and wearunder dynamic stresses. Dry lubricating film by tumbling into the sealingsurface (silvery colour) Friction force reduction in conjunction with lowdynamic stresses Long-term friction reduction can be achieved bydeposition of the slide-promoting substances inhollows in the opposing surface Improved separation in automatic assembly Low abrasion resistance of MoS 2 layer Rubbing of the surface layer can lead to dirt build upon the automatic assembly machine peripherals For all types of elastomers Article group OMElastolub 013 coatingElastolub 013 is a silicone fluid-based lubricant.

O-RingE General quality criteria and storage guidelinesE.1 Quality criteriaThe cost-effective use of seals and bearings is highlyinfluenced by the quality criteria applied in production.Seals and bearings from Busak+Shamban arecontinuously monitored according to strict qualitystandards from material acquisition through to delivery.Certification of our production plants in accordance withinternational standards QS 9000 / ISO 9000 meets thespecific requirements for quality control andmanagement of purchasing, production and marketingfunctions.Our quality policy is consistently controlled by strictprocedures and guidelines which are implemented withinall strategic areas of the company.All testing of materials and products is performed inaccordance with accepted test standards andspecifications, e.g. random sample testing in accordancewith DIN ISO 2859, part 1.Inspection specifications correspond to standardsapplicable to individual product groups (e.g. for O-Rings:ISO 3601).Our sealing materials are produced free ofchlorofluorinated hydrocarbons and carcinogenicelements.The tenth digit of our part number defines the qualitycharacteristics of the part. A hyphen indicates compliancewith standard quality criteria outlined in this catalogue.Customer-specific requirements are indicated by adifferent symbol in this position. Customers who requirespecial quality criteria should contact their localBusak+Shamban sales office for assistance. We haveexperience in meeting all Customer quality requirements.E.2 Storage and shelf lifeSeals and bearings are often stored as spare parts forprolonged periods. Most rubbers change in physicalproperties during storage and ultimately becomeunserviceable due, e.g., to excessive hardening,softening, cracking, crazing or other surfacedegradation. These changes may be the result ofparticular factors or combination of factors, such as theaction of deformation, oxygen, ozone, light, heat,humidity or oils and solvents.With a few simple precautions, the shelf life of theseproducts can be considerably lengthened.Fundamental instructions on storage, cleaning andmaintenance of elastomeric seal elements are describedin international standards, such as:DIN 7716 / BS 3F68:1977,ISO 2230 orDIN 9088The standards give several recommendations for thestorage and the shelf life of elastomers, depending on thematerial classes.The following recommendations are based on the severalstandards and are intended to provide the most suitableconditions for storage of rubbers. They should beobserved to maintain the optimum physical and chemicalvalues of the parts:HeatThe storage temperature should preferable be between+5 C and +25 C. Direct contact with sources of heatsuch as boilers, radiators and direct sunlight should beavoided.If articles are taken from low temperature storage, careshould be taken to avoid distorting them during handlingat that temperature as they may have stiffened. In thiscase the temperature of the articles should be raised toapproximately +20 C before they are put into service.HumidityThe relative humidity in the store room should be below70 %. Very moist or very dry conditions should beavoided. Condensation should not occur.LightElastomeric seals should be protected from light sources,in particular direct sunlight or strong artificial light with anultraviolet content. The individual storage bags offer thebest protection as long as they are UV resistant.It is advisable to cover any windows of storage rooms witha red or orange coating or screen.RadiationPrecaution should be taken to protect stored articles fromall sources of ionising radiation likely to cause damageto stored articles.136

O-RingOxygen and ozoneWhere possible, elastomeric materials should beprotected from circulating air by wrapping, storage inairtight containers or by other suitable means.As ozone is particular deleterious to some elastomericseals, storage rooms should not contain any equipmentthat is capable of generating ozone, such as mercuryvapour lamps, high voltage electrical equipment, electricmotors or other equipment which may give rise to electricsparks or silent electrical discharges. Combustion gasesand organic vapour should be excluded from storagerooms as they may give rise to ozone via photochemicalprocesses.DeformationElastomeric materials should, wherever possible, bestored in a relaxed condition free from tension,compression or other deformation. Where articles arepacked in a strain-free condition they should be stored intheir original packaging.Shelf life and shelf life controlThe useful life of a elastomeric seals will depend to a largeextend on the type of rubber. When stored under therecommended conditions (above sections) the belowgiven shelf life of several materials should be considered.AU, thermoplasticsNBR, HNBR, CREPDMFKM, VMQ, FVMQFFKM, Isolast PTFE4 years6 years8 years10 years18 yearsunlimitedElastomeric seals should be inspected after the givenperiod. After this giving an extension period is possible.Rubber details and components less than 1.5 mm thickare liable to be more seriously affected by oxidationdegradation even when stored in satisfactory conditionsas recommended. Therefore they may be inspected andtested more frequently than it is mentioned above.Contact with liquid and semi-solid materialsElastomeric seals should not be allowed to come intocontact with solvents, oils, greases or any other semi-solidmaterials at any time during storage, unless so packed bythe manufacturer.Contact with metal and non-metalsDirect contact with certain metals, e.g. manganese, ironand particularly copper and its alloys, e.g. brass andcompounds of these materials are known to havedeleterious effects on some rubbers. Elastomeric sealsshould not be stored in contact with such metals.Because of possible transfer of plasticisers or otheringredients, rubbers must not be stored in contact withPVC. Different rubbers should preferably be separatedfrom each other.Rubber details / seals in assembled componentsIt is recommended that the units should be exercised atleast every six months and that the maximum period arubber detail be allowed to remain assembled within astored unit, without inspection, be a total of the initialperiod stated above and the extension period. Naturallythis will depend on the design of the unit concerned.CleaningWhere necessary, cleaning should be carried out with theaid of soap and water or methylated spirits. Water shouldnot, however, be permitted to come into contact withfabric reinforced components, bonded seals (because ofcorrosion) or polyurethane rubbers. Disinfectants orother organic solvents as well as sharp-edged objectsmust not be used. The articles should be dried at roomtemperature and not placed near a source of heat.137
