Product Description


FKM O Ring Hot Sell Cutomerized HNBR FKM NBR SILICONE EPDM O-Ring


FKM® or fluorocarbon elastomers were first introduced in the mid 1950's. Since then they have become of major importance in the seal industry. Due to its good chemical resistance, high temperature range and its low compression set, fluorocarbon rubber is the most significant single elastomer development in recent history. The working temperature range ifor FKM® is considered to be -15 to +400 degrees F (-29 to +204 degrees C), but it will take temperatures up to 600 degrees F (316 degrees C) for short periods of time. Du Pont's Kalrez® is normally recommended up to 500 degrees F (260 degrees C). On the low end, FKM® compounds have been known to seal at -65 degrees F (-54 degrees C) in some special static applications, however the normal low temperature limit is -15 degrees F (-26 degrees C). Fluorocarbon 0-rings should be considered for seal use in aircraft, automobile, scientific instruments and other mechanical devices requiring maximum resistance to elevated temperature and to many functional fluids. They are widely used in diffusion pumps on vacuum systems and on vacuum flanges on mass spectrometers and electron microscopes. FKM® is recommended for most applications and Kalrez® is only used where the additional temperature range can be justified by the increased cost.


FKM® and Kalrez® are 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.

FKM is not recommended for:

  • Ketones (MEK). Skydrol fluids.
  • Amines (UDMH), anhydrous ammonia.
  • Low molecular weight esters and ethers.
  • Hot hydrofluoric or chlorosulfonic acids.
Application: mainly used in manufacturing all kinds of oil-resistant products, such as rubber hoses and seals, etc.


ORK offers the seal industry's largest inventory of o-rings, which includes every standard AS568 and ISO 3601 size, and the following:

Description: Presently the seal industry's most widely used and economical elastomer, Nitrile combines excellent resistance to petroleum-based oils and fuels, silicone greases, hydraulic fluids, water and alcohols, with a good balance of such desirable working properties as low compression set, high tensile strength, and high abrasion resistance.


Key Use(s): Oil resistant applications of all types. Low temperature military uses. Off-road equipment. Automotive, marine, aircraft fuel systems. Can be compounded for FDA applications.


Temperature Range:

Standard Compound: -30° to +120°F

Hardness (Shore A): 40 to 90.

Features: Comprised of the copolymer butadiene and acrylonitrile, in varying proportions. Compounds can be formulated for service temperature ranging from -85°F to +275°F. Use of Carboxylated Nitrile can have superior abrasion resistance, while still having improved oil resistance.

Limitations: Nitrile compounds are attached by small amounts of Ozone. Phthalate type plasticizers are commonly used in compounding Nitrile Rubber. These plasticizers can migrate out and cause problems with certain plastics. Also, new regulations on certain phthalates have limited their use.
