Fluorocarbon elastomers have grown to major importance in the sealing industry. Due to its wide range of chemical compatibility, temperature range, low compression set, and excellent aging characteristics, fluorocarbon rubber is the most significant single elastomer developed in recent history. Fluorocarbon elastomers are highly fluorinated carbon-based polymers used in applications to resist harsh chemical and ozone attack. - The working temperature range is considered to be -26°C to +205°/230°C (-15°F to +400°/440°F).
- For short working periods it will take even higher temperatures.
- Special compounds having improved chemical resistance are also available with new types always being developed in our own R&D centers.

FKM applications
Fluorocarbon O-rings should be considered for use in aircraft, automobile and other mechanical devices requiring maximum resistance to elevated temperatures and to many fluids. FKM (FPM, Fluorel®) resist mineral oils and greases, aliphatic, aromatic and also special chlorinated hydrocarbons, petrol, fuels, silicone oils and greases. It is suitable for high vacuum applications. Many fluorocarbon compounds have a higher than normal mold shrinkage rate, molds for fluorocarbon products are often different from molds for Nitrile.
Generally speaking, with increasing fluorin content, resistance to chemical attack is improved while low temperature characteristics are diminished. There are, however, specialty grade fluorocarbons that can provide high fluorin content with low temperature properties.Rubber Connector Seal are available in the following elastomers:
Aflas® or Kalrez®(FFKM)
Acrylate Rubber(ACM)
Butyl Rubber(IIR)
Ethylene-propylene (EPR, EPDM)
Ethylene Acrylate Rubber(AEM)
Fluorocarbon (FKM/FPM)
Fluorosilicone(FVMQ)
Hydrogenated Nitrile (HNBR)
Liquid Silicone Rubber(LSR)
Neoprene Rubber(CR)
Nitrile Rubber (Buna-N/NBR)
Natural Rubber(NR)
Polyurethane(PU)
Silicone Rubber Styrene-butadiene Rubber (SBR)Different elastomers have different compatibility with various chemical elements and their characteristics. See the table below for more material knowledge to order the most cost-effective o-rings from us.
