O-RINGS 

Used for sealing in valves, faucets, transmissions, compressors, cylinders, and flanges. Also used for small drive belts. 

BUNA-N-70 DUROMETER 

(NITRILE) BLACK 

Due to its excellent resistance to petroleum products, 

and its ability to be compounded for service over a 

temperature range of -65° to +275°F (-54°to 

+135°C), nitrile is the most widely used elastomer in 

the seal industry today. Most military rubber specifications 

for fuel and oil resistant MS and AN O-rings 

require nitrile base compounds. It should be mentioned, 

however, that to obtain good resistance to low 

temperature with nitrile compounding, it is almost 

always necessary to sacrifice some high temperature 

fuel and oil resistance. 

Nitrile compounds are superior to most elastomers 

with regard to compression set or cold flow, tear, and 

abrasion resistance. Inherently, they do NOT possess 

good resistance to ozone, sunlight or weather 

but this has been substantially improved through 

compounding. 

Nitrile is recommended for: 

• General purpose sealing. 

• Petroleum oils and fluids. 

• Water. 

• Silicone greases and oils. 

• Di-ester base lubricants (MIL-L-7808). 

• Ethylene glycol base fluids (Hydrolubes). 

MOST POPULAR GENERAL PURPOSE 

• Four thicknesses available: 1/16, 3/32, 1/8, 3/16 

– THREE COMPOUNDS AVAILABLE – 

VITON-75 DUROMETER 

(FLUOROCARBON) BLACK 

Fluorocarbon elastomers were first introduced in the 

mid-1950’s. Since then they have grown to major 

importance in the seal industry. Due to wide spectrum 

chemical compatibility and temperature range, fluorocarbon 

rubber is the most significant single elastomer 

development in recent history. 

Its working temperature range is considered to be from 

-20° to +400°F (-29° to +204°C) but it will take temperatures 

up to 600°F (316°C) for short periods of time. It 

has been known to seal at -65°F (-54°C) in some static 

applications. Newer developments have tremendously 

improved the compression set characteristics of this 

very useful material. 

Compounds made from fluorocarbon elastomers 

should be considered for use in aircraft, automotive 

and other mechanical devices requiring maximum 

resistance to deterioration by test and functional fluids. 

Fluorocarbon is recommended for: 

• Petroleum oils. 

• Di-ester base lubricants 

(MIL-L-7808, MIL-L-6085). 

• Silicate ester base lubricants 

(MLO 8200, MLO 8515, OS-45). 

• Silicone fluids and greases. 

• Halogenated hydrocarbons (carbon 

tetrachloride, trichloroethylene). 

• Selected phosphate ester fluids. 

• Acids. 

FOR MAXIMUM TEMPERATURE AND 

CHEMICAL RESISTANCE 

ETHYLENE PROPYLENE 70 

DUROMETER 

(EPR, EPDM) BLACK 

Ethylene has won broad acceptance in the selling 

world because of its excellent resistance to Skydrol 

and other phosphate ester type hydraulic fluids. 

Ethylene propylene has a temperature range of -65° 

to +300°F (-54° to +150°C) for most applications. 

EP is recommended for: 

• Phosphate ester base hydraulic fluids 

(Skydrol, Fyrquel, Pydraul). 

• Steam (to 500°F) (260°C). 

• Water. 

• Silicone oils and greases. 

• Dilute acids. 

• Dilute alkalies. 

• Ketones (MEK, acetone). 

• Alcohols. 

• Automotive brake fluids.

SQUARE CUT O-RINGS 

THE SEAL FOR ALL STATIC APPLICATIONS 

Hydraulic fluids, lubricating oils, gasoline, mineral oil, diesel fuel, pneumatic service. 

● Made from Buna-N* 70 

● Interchangeable with standard O-rings, size for size, from 3/16” 

up to 18” ID. 

● Fit the same gland as standard O-rings. 

● Outperforms and outlasts standard O-rings in most static applications. 

● Offered in the same material selection as standard O-rings; meets 

ASTM and SAE requirements. 

● Closer cross-sectional tolerances can be held on the square cut than 

on most standard O-rings. 

● Temperature range: -40°F to 300°F.

* Buna-N is the most widely used synthetic rubber for O-ring seals. Its wide acceptance as a sealing material is due to its economic cost, 

inherent resistance to petroleum-based products and dependability over a temperature range which covers most industry applications.
