What is a FEPM O-ring?

Perfluoroelastomers have PTFE-similar chemical and heat resistance. They combine these positive properties of an O-ring from PTFE (Tetrafluoroethylene-propylene rubber) with the elastic behavior of an O-ring from FKM. Due to the considerably higher price level of this material group, perfluoro elastomers are only used if other materials can no longer meet the requirements and if safety aspects justify the higher costs. The main application areas are oilfield and chemical applications.

The advantage of FEPM:

  • Resistant to high temperatures
  • From 0 ºC to +235 ºC
  • good chemical resistance
