Kalrez® FFKM Seals for Medical and Pharma Applications
Kalrez® FFKM seals for medical and pharma applications are engineered for high purity environments where chemical resistance, biocompatibility, and contamination control are critical. These perfluoroelastomer sealing solutions are used in O-rings, gaskets, and custom parts installed in pharmaceutical processing equipment, medical devices, and clean room systems exposed to aggressive chemicals, sterilization cycles, and sensitive product streams. Kalrez® FFKM materials provide excellent resistance to CIP and SIP processes while maintaining low extractables and stable sealing performance in critical applications.
Canyon Components supplies Kalrez® FFKM seals alongside Canrez® perfluoroelastomer alternatives, offering a competitively priced solution with fast lead times and extremely high quality. Our team supports material selection based on chemical exposure, temperature range, and compliance requirements such as USP Class VI, ISO 10993, and FDA CFR 21.177.2600 to ensure reliable performance in medical and pharmaceutical systems.

Features of Kalrez® FFKM Seals for Medical and Pharma Applications
- FFKM materials maintain sealing integrity during repeated sterilization cycles including steam and chemical cleaning
- Kalrez® FFKM seals offer low compression set, supporting long-term sealing reliability in critical systems
- High purity FFKM materials exhibit low extractables and low outgassing, helping minimize contamination risk
- Kalrez® FFKM seals can meet compliance requirements such as USP Class VI, ISO 10993, and FDA standards
Limitations of Kalrez® FFKM Seals for Medical and Pharma Applications
- Kalrez® FFKM seals have a higher cost compared to EPDM, silicone, and other medical-grade elastomers
- Lead times may vary depending on compound selection and part geometry
- Low temperature flexibility is limited compared to silicone and other low temperature elastomers
- Mechanical properties may be lower than reinforced elastomers in high-wear applications
- Over-specifying FFKM seals in less demanding applications can increase cost without added performance benefit
