O-Ring FFKM (PERFLUOROELASTOMER)

Perfluoroelastomer(FFKM) parts resist over 1,800 different chemicals, while offeringthe high temperature stability of PTFE (327°C).

FFKM use in highly aggressive chemical processing, semiconductor wafer fabrication, pharmaceutical, oil and gas recovery, and aerospace applications. The long-term, proven performance of FFKM parts can meanless frequent seal changes, repairs and inspections, increasing process and equipment up time for greater productivity and yield.
