Product Detail

Perfluoroelastomer FFKM Rubber O Ring

FFKM O rings have excellent resistance to extreme temperatures, -10°C to +260°C. Some special compounds can operate beyond 316°C. FFKM O ring are resistant to nearly all chemicals. These include inorganic acids, alkalines, ketones, esters, alcohols, fuels, and hot waters. They can be used for applications in aggressive chemical environments, FFKM used 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 mean less frequent seal changes, repairs and inspections, increasing process and equipment uptime for greater productivity and yield.FFKM O ring also provides low outgassing in vacuum-sealing application
