FFKM O-Rings Overview
FFKM (Perfluoroelastomer) O-Rings are the highest performing sealing solution available today.
Compared with all other elastomer materials, FFKM O-Rings combine exceptional chemical resistance with outstanding high temperature stability up to +340°C.
This unique combination makes them the preferred choice for critical applications in chemical processing, semiconductors, pharmaceuticals, and oil & gas industries.
In addition, FFKM O-Rings retain full elasticity, enabling their reliable use as flange seals, piston seals, and rod seals even under extreme conditions.
