FKM, FPM (Viton, Fluorel)

  • FKM 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 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). But for short working periods it will take even higher temperatures.
  • FKM resist mineral oils and greases, aliphatic, aromatic and also special chlorinated hydrocarbons, petrol, diesel fuels, silicone oils and greases.
  • Disadvantage: too expensive. Especially perfluoroelastomer(FFKM).
