Standard O-Ring Material Applications
 
We offer the following six (6) standard rubber materials in a range of durometer (Shore A) hardnesses to 
satisfy practically any service condition:
 
Viton® / FKM: 
 
Fluorocarbon (Viton®) exhibits exceptional resistance to chemicals, oils, temperature 
extremes (-13°F to +446°F), low compression set, low gas permeability and excellent aging characteristics. 
Applications include: aircraft engines, automotive fuel handling systems, and chemical processing industries. 
FKM is also suitable for high vacuum applications. It is not recommended for exposure to ketones, alkalis, 
and Skydrol® fluids. Custom compounds are available with improved chemical and low temperature 
resistance. Read More
 
Nitrile / NBR: 
 
Nitrile (Buna-N) is the most widely used elastomer due to its excellent resistance to petroleum 
products, operating temperature range (-40°F to +257°F) and one of the best performance-to-cost values. 
It's an ideal material for aerospace, automotive, propane and natural gas applications. Special Hydrogenated 
Nitrile (HNBR) compounds can improve resistance to direct ozone, sunlight, and weather exposure while 
increasing temperature range to +300°F. Read More
 
Ethylene-Propylene / EPDM: 
 
EPDM has outstanding resistance to heat, water and steam, alkali, mild acidic 
and oxygenated solvents, ozone, and sunlight (-40ºF to +275ºF); but it is not recommended for gasoline, 
petroleum oil and grease, and hydrocarbon environments. This popular rubber compound is usually the 
first choice for low torque drive belt applications. Read More
 
Fluorosilicone / FVMQ: 
 
Fluorosilicone (-75º to +400ºF) combines the good high and low temperature 
stability of silicones with the fuel, oil, and solvent resistance of fluorocarbons. FVMQ is unparalleled for 
aerospace fuel systems, auto fuel emission control systems and to meet or exceed government, military, 
aerospace, automotive, industrial and commercial specifications. However, due to relatively low tear 
strength, high friction and limited abrasion resistance of these materials, they are generally not used in 
dynamic applications. They are also not recommended for exposure to brake fluids, hydrazine, or ketones. 
 
Silicone / VMQ: 
 
In the Silicone family, you will find compounds which are superior as static seals in extreme 
temperature conditions. Standard compounds handle operating temperatures -85º to +400ºF. Silicone 
compounds are popular in food and medical applications because they are very clean and do not impart odor 
or taste. Special Phenyl silicones can be used down to -148°F. Read More
 
Neoprene® / CR: 
 
Neoprene (-40º to +250ºF) is reasonably priced and features good resistance to petroleum 
oils, ozone, sunlight and oxygen aging, relatively low compression set, good resilience and outstanding 
physical toughness. It is the preferred sealing material for the refrigeration industry because of its resistance to 
ammonia and Freon®. Read More
 
Let us know if you require materials to meet the following standards; UL, MIL, AMS, ASTM, FDA 21 CFR 
177.2600, USP Class VI, or ISO 10993. We have many special compounds that can meet the specification 
you are looking for.
