General Information
A Word About Advanced
Polymer Seals
Seals Design
Thank you for giving CoorsTek the opportunity
to consult on your sealing application.
You'll find this catalog is easy to use for selecting
standard piston and rod seals because each
installation drawing shows the complete dimensioning
of seal glands, as well as mating rods
and cylinders.
The seal configurations also reference, where
applicable, the appropriate military packing
gland specification. Thus, there are CoorsTek
seals for the current MIL-G-5514F gland designs
as well as replacements for seals designed to
operate in MIL-P-551, A through E revision
glands.
Some seals shown in this catalog are for
use in modified military/aerospace glands
and industrial/commercial standards. Some of
those used in the earlier MIL-P-5514 revisions
are considered inactive for new military designs
but can be considered for industrial service. The
MIL-G-5514 designs, "Heavy-Duty Service", are
more appropriate for current fluid-power systems,
which require longer seal life and longer
periods of operation at elevated temperature.
Materials
The material property charts will assist you in
selecting the right material for the job. While
such charts are helpful, they should be not be
considered the ultimate authority but should be
used as a guide only. In the long run, the best
authority is the experience designers invest in
literally thousands of seals for aircraft, military,
and industrial applications. Let CoorsTek get
involved at the outset of your design and we will
save you a lot of time and money.
Particular notice should be given to the materials
of construction for the various seals.
Although material selection and seal configuration
are somewhat interdependent, the seal
material specified on the drawings is more often
the result of CoorsTek producing most of that
particular configuration in that particular material.
But changes in operating conditions could
have a significant effect on the choice of material
to use for the seal. Please contact CoorsTek
Engineering for assistance.
CoorsTek has devised a simple, easily identifiable
code for changing materials within a
given part number. The Material Property Chart
depicts the more commonly used of about 100
materials used in seal design. For example (the
basic material for Part Number TF731 shown
on page 50 is molybdenum-disulfide-filled PTFE
and, thus, the callout for the -214 size is specified.)
CoorsTek uses fluorocarbon resins, known
generically as polytetrafluoroethylene
(PTFE). There are many manufacturers of PTFE
resins today. CoorsTek processes these resins
and fabricates finished parts for customers
throughout the world …and has been doing this
for almost half a century.
I
n addition, there are several authoritative
works on the subject of PTFE and PTFE blends
which have been published by manufacturers
of fluorocarbon resins. These publications are
available to you through your CoorsTek representative.

Seals Selector Handbook
General Information
PTFE seals provide the lowest coefficient of
friction available, as well as other excellent
mechanical properties including low moisture
absorption, dielectric strength, chemical resistance,
and operation at extreme temperatures.
Some seals are designed to prevent blowout or
extrusion of a rubber O-ring at high pressures or
under rapid reversals of pressure. Others, such
as PTFE O-rings, make excellent static seals under
a wide variety of design conditions.
CoorsTek Tetralon ® materials, both blended
and virgin, are made from specialty PTFE
resins processed for their extremely longwearing
properties. Blended Tetralon ® resins
containing fillers such as graphite, bronze, glass,
or molybdenum disulfide are manufactured to
enhance the various physical and mechanical
properties of the seals.
Virgin PTFE resins are extremely pure and are
molded without fillers. Historically, material
standard MIL-R-8791 has been relied upon
by seal designers when virgin PTFE is required.
CoorsTek Virgin Tetralon ® PTFE meets or exceeds
the MIL-R-8791 material specification.
In addition, Revision D to MIL-R-8791 specifically
excludes the use of reprocessed material.
As a result, CoorsTek does not approve
the use of reprocessed PTFE. Therefore, any
specification referring to MIL-R-8791, under any
revision, will be interpreted by CoorsTek as a requirement
for a premium grade virgin Tetralon ®
PTFE.
Another common specification, AMS3651,
does allow the use of reprocessed material.
The design engineer must be very selective in
his choice of suppliers to be sure he is getting
premium virgin PTFE when it is required.
T etralon® material is virgin PTFE, and is a
registered trademark of CoorsTek, Inc. and is
known for its long-wearing material which also
embodies superior anti-extrusion and dimensional
stability properties. This material is colorcoded
blue by means of a special dye. It should
be noted that, in some applications. Tetralon ®
will wear for a very long time as a most effective
seal after a few "wearing in" cycles to burnish the
cylinder or rod.
Glass fiber is widely used filler for PTFE seals.
Depending upon the amount used (which
is commonly either 15% or 25% by weight), it
is most beneficial in improving resistance to extrusion
and cold flow but at the expense of low
breakaway friction and elongation. Care should
be taken when selecting any glass fill so that the
seal does not create an excessive wear problem
if the mating surface is aluminum or other relatively
soft material.
T etralon® 300 material is formulated without
any abrasive fillers and thus overcomes the
problems associated with sealing against soft
mating surfaces. This material offers an impressive
wear ratio of 1000:1 over unfilled PTFE, as
well as thermal stability exceeding that of conventionally
filled PTFE. Tetralon ® 300 has been
qualified as the standard seal material on many
current aircraft systems.

Seals Selector Handbook
General Information
Graphite filler may be compounded with PTFE
for high-load-carrying applications where
initial wear and general strengthening characteristics
must be provided. It is most often recommended
for use in water or water-based fluids.
Bronze is added to PTFE resins and has been
shown to increase substantially the wear
resistant properties of seals, especially in longstroke,
highly loaded applications. Tetralon ®
050, a proprietary CoorsTek compound which
utilizes a bronze filler, is an excellent bearing
material, with one of the best wear factors of any
filled composition known. The designer must be
careful when using this material in certain corrosive
environments where the bronze may be
subjected to chemical attack or in those applications
where dielectric strength is critical.
There are several PTFE materials compounded
by CoorsTek for seal and bearing applications.
In general, the selection of a seal material
may be made by the experienced designer, but
when there is some question about usage, or
you desire assistance in the selection, please
contact us as early in the design stage as possible.
CoorsTek Engineering can provide you with
historical data and help get your system design
off to a good start.
Features
CoorsTek patented MiniGroove ® feature can
be supplied on most sealing surfaces. This
exclusive process helps seal against low pressures
and yields even lower friction coefficients
than normally available.
"MiniGrooving" is an exclusive secondary machining
operation used to create very fine multiple
peaks and valleys on the circumference of
the sealing face. This proprietary process results
in high unit loading of the seal even at low force
levels to significantly reduce low-pressure leakage.
In addition, the grooves act as resevoirs to
retain a volume of lubricating fluid, thus minimizing
wear.
M iniGroove® features can be ordered on any
CoorsTek rod or piston seal by adding "M"
after the basic part number (see design charts).
Side wall notches are an optional feature of
CoorsTek seals. CoorsTek recommends
sidewall notches for dynamic seals used in bidirectional
pressure applications. These sidewall
notches assure rapid response of the seal to
pressure surges and sudden pressure reversals.
Sidewall notches are sometimes recommended
on PTFE seals to prevent possible side wall sealing.
CoorsTek seals are designed with sufficient
end clearance so that positive pressure under
the seal is maintained. Notching of CoorsTek
seals used in single-acting pistons or rod seals
is not normally required.
Ordering Information
The installation drawings shown in this catalog
contain complete ordering information.
Parts that are approved for use by The Boeing
Company may be ordered either by the CoorsTek
part number or Boeing part number and the
drawing notes consider either selection.

Properties
This polymer is a co-polymer of ethyl acrylate or butyl acrylate and a small amount of monomer which facilitates
vulcanization. ACM has excellent resistance to heat, hydrocarbon oils, mineral oils, oxidation and ozone,
but poor resistance to water, steam, acids and alkalis. Normal service temperature of ACM is between -25°C
and +175°C.
AFLAS, a registered trademark of the Asahi Glass Co., is a copolymer to TFE and propylene. It is used in
oil-field applications because of its resistance to hydrogen sulfide, amines, acids, and steam. Claimed high
temperature capability to +300°C in some situations. Also has used in the semiconductor industry.
These are high molecular weight organic materials having large number of urethane (NH-C-OO) groups. The
polyester polyurethanes are referred to as AU. These materials can be made from as low as 40 shore-A up
to 80 shore-D, to match various customer specifications. Normal service temperatures of these polymers is
between -30°C and +80°C.
The general properties of these materials are:
-High mechanical properties, excellent abrasion resistance and good flexibility
-Very good resistance to ozone and oxidation
-Good resistance to mineral oils greases and aliphatic hydrocarbons
In comparison with other elastomers, polyurethane exhibits outstanding mechanical and physical properties.
It is particularly noted for high tensile strength, outstanding wear and abrasion resistance, and for excellent
resistance to extrusion.
RECOMMENDED FOR: Petroleum based fluids, hydrocarbon fuels, oxygen and ozone, and other weathering agents.
NOT RECOMMENDED: High temperature (max. +122°C), hot water, acids, ketones, and chlorinated hydrocarbons.
The inherent toughness and abrasion resistance of polyurethane seals are particularly desirable in hydraulic
systems involving high pressures, shock loads, and abrasive contamination. Often used for rod scrapers and
seals. Temperature limits its use in aerospace applications.
Polymers Range: Polychloroprene rubber (CR). This polymer is based on 2-chloro-1, 3 butadiene and is commonly
referred to as neoprene. The chief characteristics of the polymer are flame retardancy, excellent aging
properties in ozone and weather environments along with resistance to abrasion and flex fatigue. Polychloroprene
exhibits good resistance to mineral oils with high aniline point, greases, refrigerants, and water.
These are basically homopolymers of chloroprene and are among the oldest synthetic rubbers available.
RECOMMENDED FOR: Refrigerants, high aniline paint oils, silicate ester lubricants, water, and air.
NOT RECOMMENDED: Phosphate ester fluids, ketones.
Neoprene remains one of the most widely used synthetic elastomers. Although usage in the seal industry has
diminished it is used in large quantity for other rubber parts.
This polymer, based on polyethylene, has chlorine side groups and chloro sulphonated side groups on the main
chain. It is commonly referred to as Hypalon ® material. Vulcanizates of this polymer have very good resistance
to flame, heat, ozone, and weathering. They also have good resistance to swelling in hot water, steam,
acids, bases, ketones, polar organic media, and oxidizing media. Normal service temperatures for this polymer
are between -20°C and +150°C. Hypalon is a registered trademark of E.I. du Pont Nemours and Company, and
is commonly referred to for all kinds of CSM.
This is a terpolymer of ethylene, ethyl acrylate, and a cure site monomer. Vamac ® polymer is a popular EAM
Polymers Range: Ethylene acrylate rubber (EAM). This polymer has better heat resistance than ACM. Other
properties include good low-temperature flexibility, good resistance to weathering, sunlight, oxygen and
ozone, and good flame resistance. It has good resistance to paraffin based mineral oils, water, and refrigerants.
Normal service temperature of AEM is between -40°C and +175°C. Vamac ® is a registered trademark
of E.I. du Pont de Nemours and Company or its affiliates.
This is a co-polymer of epichlorohydrin and ethylene oxide. ECO vulcanizates have very low permeability to
gases and good resistance to weathering and ozone. They exhibit good resistance to mineral oils, greases,
vegetable oils, aliphatic hydrocarbons, petroleum, and water. Normal service temperature for this polymer is
between -40°C and +150°C.
This polymer is a terpolymer of ethylene, propylene and some diene as the termonomer.
Molded parts and seals from EPDM have good resistance to:
-Ozone, aging, and weathering
-Water and steam
-Dilute acid, alkalies, ketones, alcohols, and polar organic media
-Phosphate ester based hydraulic fluids

NITRILE OR BUNA-N
(NBR)
NYLON
POM
Properties
This versatile group of polymers is used for a vast array of sealing applications because of its resistance to
a broad spectrum of chemical and oil media, and a wide range of temperatures. For many years, FKM was
only known as Viton ® material. However, other manufacturers also have excellent versions of FKM materials,
generically known as fluoroelastomers. The various types of FKM materials are copolymers of hexafluoropropylene
(HFP) and vinylidine difluoride (VF2, fluorine content = 65-66%). While terpolymers have tetrafluoroethylene
(TFE) as the termonomer (fluorine content = 67-71%), some terpolymers have an additional cure site
monomer which are used for speciality applications. FKM exhibits excellent resistance to mineral oils, fuels,
steam, alcohols, alcohol containing fuels, aliphatic, and
aromatic hydrocarbons. Chemical and oil resistance improves as the fluorine content of these polymers
increase. However, the co-polymer types of FKM give the best compression set resistance. Normal service
temperatures for FKM are between -20°C and +250°C. FKM is based upon monomers vinylidine fluoride,
hexafluorapropylene and tetrafluoroethylene. FKM exhibits high-heat resistance (260°C) and is combined with
good chemical resistance and compression set properties.
RECOMMENDED FOR: Petroleum based hydraulic fluids, diester and silicate ester base lubricants, acids, select
phosphate ester fluids, and halogenated hydrocarbons.
NOT RECOMMENDED FOR: Skydrol ® , amines, ketones, steam/hot water, anhydrous ammonia, acids hydrofluoric
and chlorosulfonic, and low temperature sealing.
Skydrol ® is a registered trademark of the Eastman Chemical Company. Viton ® is a registered trademark of
Lautsprecher Teufel GmbH.
FVMQ has a similar polymer stucture as that of VMQ and has an additional fluoro substitute group on the polymer
chain. These polymers have very good fuel, oil and solvent resistance in addition to the regular properties
of silicones. They are used for special applications.
The elimination of double bonds from the polymer chain of NBR, either partially or completely by hydrogenation,
gives hydrogenated nitrile rubber. These polymers have much more improved heat resistance than NBR
(heat resistance depends on the degree of hydrogenation). HNBR has outstanding resistance to heat, ozone,
weathering, mineral oils, crude oils with amines, fuels, greases, aliphatic hydrocarbons, and industrial chemicals.
HNBR has very good mechanical properties and excellent wear resistance. Normal service temperatures
for these polymers are between -30°C and +150°C.
These polymers mainly consist of isobutylene with a small amount of isoprene. The IIR elastomers have low
gas permeability and good resistance to ozone and weathering. They have good resistance to glycol-based
fluid acid, bases, and steam. The halogenated butyls (i.e CIIR & BIIR) exhibit lower gas permeability, better
resistance to ozone, weathering chemicals, and, above all, better heat resistance than IIR. The normal service
temperatures for these polymers is between -40°C and +145°C.
This polymer, which is commonly referred to as Nitrile or Buna-N, is a co-polymer of butadiene and acryonitrile.
They are differentiated based on the percentage of bound acryonitrile (ACN) content in the polymer.
The low ACN polymers have good low temperature flexibility, compression set resistance, and good elastic
properties but moderate resistance to oils and fuels. As the ACN content increases, resistance to mineral oils,
fuels, and greases increases but properties such as low temperature flexibility, compression set resistance,
and elasticity deteriorate. Medium ACN polymers exhibit good balance of all the above properties. Normal
service temperatures of these polymers are between -25°C and +120°C.
These are basically homopolymers of chloroprene and are among the oldest synthetic rubbers available.
RECOMMENDED FOR: Refrigerants, high aniline paint oils, silicate ester lubricants, water, and air
NOT RECOMMENDED: Phosphate ester fluids, ketones
This family of thermoplastics is widely used for anti-extrusion purposes and other sealing applications. Nylon
is resistant to various petroleum and phosphate-ester-based hydraulic fluids. Normal service temperatures
are between -50°C and +120°C.
This thermoplastic material is also referred to as polyacetal. This material has good stiffness, hardness and
strength and has the ability to take very high loads. In certain applications it can replace metal parts like brass
and aluminium. It also exhibits better dimensional stability than other thermoplastics in moist condition due to
its very low water absorption. Normal service temperatures of this material is between -40°C and +140°C.

Properties
This homopolymer, polytetrafluoroethylene, is generically known as PTFE, but for many years was only marketed
by Du Pont as Teflon ® material. However, many other polymer manufacturers, such as 3M, also have excellent
versions of PTFE. This non rubbery material has many outstanding properties. Its chemical resistance
is superior to any other thermoplastic or elastomer and it has excellent resistance to swelling in almost all
known media. This non toxic material has low co-efficient of friction and is non flammable. Its electrical insulation
properties are also outstanding. Normal service temperature of PTFE is between -270°C and +260°C.
Teflon ® is a registered trademark of E.I. du Pont de Nemours and Company or its affiliates.
This is a co-polymer of butadiene and styrene. This general purpose polymer has good resistance to dilute
organic and inorganic acids water, alcohols, and brake fluids. Normal service temperatures of this polymer is
between -40°C and +110°C.
A semi-organic polymer. Characterized by a wide service temperature range of between -60°C and +230°C,
high lubricity, extreme water repellence, aging and ozone resistance, and chemical inertness
RECOMMENDED FOR: Water, ozone, acids, certain hydrocarbons, heat, and cold
NOT RECOMMENDED: Polar fluids, most petroleum fluids
Because of the wide temperature range and chemical inertness, silicone compounds can be used in a wide
range of applications. However, because of its poor tensile strength and abrasion resistance, they are not
recommended for dynamic sealing situations.
This is a copolymer of tetrafluoroethylene and propylene. It shows much better resistance than FKM in high
pH caustics, brine solutions, amines engine oils, engine coolants, power steering fluids, corrosion inhibitors,
and gamma radiation. It also exhibits less sensitivity to changes in chemical enviroments and good electrical
insulation properties. Normal service temperatures for this polymer are between - 10°C and +280°C.
These compounds give the highest tensile strength in polyurethanes and are thermoplastic in nature. They
bridge the gap between conventional elastomers and thermoplastics. The abrasion resistance of these materials
are excellent and they have much better load-bearing capacity than conventional elastomers.
Components of TPU don't crack despite repeated bendings and have much better impact resistance than
conventional thermoplastics. They have very good resistance to aging, weathering, ozone, oxidation, water,
mineral oils, motor fuels, hydraulic fluids, and solvents. Normal service temperature of these materials are
between -15°C and +120°C.
These are high-molecular-weight poly organo siloxanes. VMQ has both vinyl and methyl substituent groups
on the polymer chain, while PVMQ has an additional phenyl substituent group on the polymer chain. These
polymers have excellent cold flexibility as well as high thermal resistance. They have excellent di-electric
properties and very good resistance to attack by oxygen, ozone, and sunlight. They however have moderate
resistance to mineral oils. The most admirable property of this polymer is its very wide service temperature
range i.e -65°C to +250°C.
X-NBR compounds are terpolymers of butadiene, acrylonitrile and methacrylic acid. Because these polymers
have caboxylic acid side groups, they are referred to as carboxylated nitrile rubber. Molded products of XNBR
have very high tensile strength, tear strength, and, above all, improved abrasion resistance over NBR. Normal
service temperatures for these polymers are between -25°C and +120°C.
BUTYL
EPICHLOROHYDRIN
ETHYLENE PROPYLENE
(EPR) (EPDM)
This elastomer has a very low permeability rate and a normal service temperature range between -55°C and
+100°C which makes it a good choice for sealing gases. It also has good resistance to phosphate ester hydraulic
fluids. Also, has fair resistance to nitrogen tetroxide making it a choice for rocket propulsion systems.
Very poor resistance to petroleum based fluids.
This elastomer has good resistance to petroleum fluids and ozone and a normal service temperature range of
between -40°C and +150°C, compression set at +150°C is poor, and very good abrasion resistance.
An elastomer consisting of monomers of ethylene and propylene, and in some cases an additional diene monomer,
EPDM exhibits excellent compression set properties and resistance to phosphate ester base hydraulic
fluids, and excellent explosive decompression resistance.
RECOMMENDED FOR: Phosphate ester-base hydraulic fluids, silicone oils and greases, brake fluids, water/
steam, select dilute acids and alkalis, ketones (MEK), alcohols, and radiation.
NOT RECOMMENDED: Petroleum based hydraulic fluids, aromatic hydrocarbons, diester lubricants.
Commercial aircraft use phosphate ester based fire resistant fluids and therefore use these compounds – also
widely used in the nuclear industry.

Polymers & Elastomers, Materials and Definition
Name
PERFLUOROELASTOMER
(FFKM)
Properties
FFKM can endure the harshest known environments, and can be supplied as O-rings. Kalrez ® material is a
commonly known FFKM. It has a high resistance to concentrated acids, alkalis, steam, organic alcohols, ketones
and esters and has a wide service temperature range from between -25°C and +300°C. Certain grades
have a maximum continuous service temperature of 325°C. FFKM also resists sudden changes in service
environments and lasts much longer than conventional elastomers, including FKM (Viton ® material). FFKM is a
completely fluorinated polymer with no reactive hydrogen positions. It is made from three or more monomers
in which the principal monomer is TFE. Proprietary second and third perfluorinated monomers enhance properties
such as compression set, steam resistance, low temperature flexibility, and high temperature stability.
It has the same compatibility as PTFE, and is used in semiconductor manufacturing. Additives may degrade its
properties. FFKM can be expensive.
RECOMMENDED FOR: Virtually all fluid media.

Unilock seal is a single acting piston or rod
seal, usually as a secondary seal in combination
with a MetaPlast ® seal as primary seal.
Unilock seal is energized by an elastomeric o-
ring (same dash as the seal). Unilock seal has
low friction, low stick-slip, minimal break-out
force, high wear resistance and low leakage at
very low pressure.

Unilock seal is a single-acting piston or rod
seal, usually as a secondary seal in combination
with a Metaplast ® seal as primary seal.
Unilock seal is energized by an elastomeric o-
ring (same dash as the seal). Unilock seal has
low friction, low stick-slip, minimal break-out
force, high wear resistance and low leakage at
very low pressure.
