Application of the standard O-ring material

We offer the following six (6) standard rubber material hardness range (Shore A) hardness, to effectively meet any conditions of use:

Viton / FKM /FFKM:

Viton (FKM) performance chemicals, oils, excellent resistance to extreme temperatures (-13 ° F to + 446 ° F), low compression set, low permeability and excellent anti-aging properties. Applications include: aircraft engines, automotive fuel handling systems, and chemical processing industries.

Viton is also suitable for high vacuum applications. It is not recommended to expose one, and Skydrol® base fluid. Custom compound with improved chemical and temperature resistance. read more for viton o rings seal.

Nitrile / NBR:

nitrile rubber (Buna-N) is an elastomer most widely used because of its petroleum products, operating temperature range has excellent resistance (-40 ° F to + 257 ° F) and the best performance and cost of a value. It is an ideal material for the aerospace, automotive, propane and natural gas applications. While increasing the temperature range up to + 300 ° F special hydrogenated nitrile (HNBR) compounds may directly increase ozone, sun and weather exposure resistance. read more

Ethylene – propylene / EPDM:

EPDM have heat, water and steam, strong base, weak acid and oxygenated solvents, ozone and sunlight (-40 ° C to + 275ºF) outstanding resistance; but it is not recommended for use in gasoline , petroleum oils, hydrocarbon environment. This popular mix is usually the preferred low-torque drive belt applications. read more

Fluorosilicone / FVMQ:

fluorine (-75º to + 400ºF) combined with good high temperature stability and low resistance silicone fuels, oils and solvents fluorocarbon. FVMQ is unparalleled aviation fuel systems, automotive fuel emission control systems, and meet or exceed government, military, aerospace, automotive, industrial and commercial specifications. However, due to the relatively low tear strength, high friction and limited abrasion resistance of these materials, they are generally not in dynamic applications. They also do not recommend exposure to brake fluid, hydrazine or ketone. read more

Silicone / VMQ:

silicone in the family, you will find that it is better than the static sealing compound under extreme temperature conditions. Standard compound processing temperature -85º to + 400ºF. Because they are very clean, not impart taste or odor silicone compound in food and medical applications popular. Phenyl silicone resin may be used in particular to reduce to -148 ° F. read more

Neoprene® / CR:

Neoprene (-40 ° to + 250ºF) at reasonable prices, and has oil, ozone, oxygen and sunlight aging, relatively low compression set, good good toughness and excellent physical toughness, . It is sealed refrigeration industry preferred material because of its resistance to ammonia and freon. read more

Let us know if you need the material meets the following certificate; UL, MIL, AMS, ASTM, FDA 21 CFR 177.2600, USP VI grade, or ISO 10993 we have to meet the specifications you are looking for a lot of specific compounds.
