O-rings made of FKM/FPM rubber have outstanding resistance to:
  • Mineral oils

  • Aliphatic and aromatic hydrocarbons

  • Chlorinated hydrocarbons

  • Concentrated and diluted acids

  • Weak alkalis


FKM O-rings provide excellent temperature resistance up to +200°C and a low temperature resistance down to -40°C depending on the type used as well as high mechanical values and outstanding ageing resistance far superior to conventional synthetic rubbers.

FKM O-rings are not resistant in:
  • Water vapour

  • Hot water

  • Glycols (e.g. brake fluids)

  • Polar solvents

  • Low-molecular organic acids
