We manufacture & distribute perfluoroelastomer o-rings, seals, and gaskets manufactured from a variety of FFKM materials.
We can provide FFKM o-rings in standard sizes as well as seals and gaskets in custom configurations to match your unique specifications.For example:cassette oil seal、Epdm orings、hydraulic cylinder gland seal、Epdm Rubber Strip
We manufacture FFKM o-rings, gaskets, and seals from three popular resins:
· DuPont Kalrez
· Chemraz
· Tecnoflon

FFKM O-Rings for Vacuum Applications
If you need reliable seals for vacuum applications, very low contamination (both outgassing and particle emissions) or high temperature (392-572°F/200-300°C) operations that require prolonged out-backing or processing times, we recommend custom-made, cleanroom-manufactured FFKM o-rings. After manufacturing, these o-rings are plasma-vacuum cleaned and/or vacuum baked to eliminate outgassing and provide vacuum leak tightness. When so treated, these FFKM o-rings can be used in UHV-pressure applications.
O-rings, seals, and gaskets manufactured from DuPont FFKM can resist more than 1,800 different chemicals and provide high temperature stability comparable to PTFE (≈621°F/327°C). FFKM is well-suited to use in the processing of highly aggressive chemicals, semiconductor wafer fabrication, pharmaceutical processing, oil and gas recovery, and aerospace applications. o-rings, gaskets, and seals provide proven, long-term performance, meaning less frequent replacement, repair, and inspection and increased process and equipment uptime for improved productivity and overall yield.
By reducing particulates, lowering extractables, and resisting degradation in harsh plasma environments, FFKM o-rings also help prevent contamination in semiconductor processing. This material also provides low outgassing in vacuum-sealing applications.
FDA-compliant Kalrez FFKM materials are available for food, beverage, and pharmaceutical processing.
