FFKM Seals
Perfluoroelastomer (FFKM) is a high-performance perfluoroelastomer sealing material used in demanding chemical and high-temperature applications, offering exceptionally broad chemical resistance, subject to the selected compound and process media. With an operating temperature range up to 327°C. International Seal supplies FFKM O-rings and seals for the most demanding industrial and high-purity applications.
FFKM is specified where other elastomers fail, in aggressive chemical environments, high-temperature processes, and applications requiring absolute purity. It is the material of choice in semiconductor fabrication, pharmaceutical processing, aerospace, and analytical instrumentation.
Material Properties
- Temperature range: -20°C to +327°C
- Near-universal chemical resistance
- Very low outgassing — suitable for vacuum applications
- Excellent plasma resistance for semiconductor applications
FFKM O-Rings & Custom Seals
International Seal supplies FFKM O-rings and specialist FFKM sealing components for applications where conventional elastomers such as FKM, EPDM or NBR cannot provide the required combination of chemical resistance, temperature capability and process reliability.
FFKM components can be sourced for standard replacement requirements and specialist applications, with compound selection based on the operating media, temperature, pressure, seal geometry and any relevant purity or documentation requirements. Send us your dimensions, drawing, existing part reference or operating conditions and we can review the requirement and provide a quotation.
