Perfluoroelastomer (FFKM) o-rings are recommended for their vast temperature range, chemical resistance in numerous aggressive applications, and long service life. Global O-Ring and Seal provides high-performance FFKM o-rings for your demanding applications. Our FFKM sealing solutions include Kalrez®, Chemraz®, and PERFREZ®.
Kalrez® perfluoroelastomer (FFKM) parts resist over 1,800 different chemicals, while offering the high temperature stability. They’re used in highly aggressive chemical processing, semiconductor wafer fabrication, pharmaceutical, oil and gas recovery, and aerospace applications. The long-term, proven performance of Kalrez® parts can mean less frequent seal changes, repairs and inspections, increasing process and equipment uptime for greater productivity and yield.
Chemraz®, the ultimate elastomer for demanding oilfield applications, gives excellent sealing performance when exposed to mixes of aggressive chemicals found downhole and is often specified by operators. Special compounds have been formulated for improved resistance to rapid gas decompression and abrasion, giving significant reductions in downtime and maintenance.
PERFREZ® has a variety of perfluoroelastomer (FFKM) compound o-rings to address very demanding sealing environments. FFKM is designed to withstand a broad range of chemicals and temperatures. PERFREZ® has also developed compounds for very high temperatures with greater thermal stability and compounds with an even broader spectrum of chemical resistance.
