High Pressure Kalrez® FFKM Perfluoroelastomer
High pressure Kalrez® FFKM perfluoroelastomer materials are engineered for sealing applications involving extreme pressures, aggressive chemicals, and elevated temperatures where standard elastomers cannot maintain long-term reliability. These perfluoroelastomer compounds are commonly used in O-rings, gaskets, and custom parts installed in valves, pumps, reactors, compressors, and high-pressure fluid systems. Kalrez® FFKM materials provide excellent chemical resistance and compression set resistance while maintaining sealing integrity under high differential pressures and demanding operating conditions.
Canyon Components supplies high pressure Kalrez® FFKM sealing solutions alongside Canrez® perfluoroelastomer alternatives, offering a competitively priced solution with fast lead times and extremely high quality. Our team supports compound selection, backup ring recommendations, and sealing design optimization to ensure reliable performance in high pressure applications involving O-rings, gaskets, and custom parts.

Features of High Pressure Kalrez® FFKM Perfluoroelastomer
- FFKM materials maintain sealing integrity at elevated temperatures often exceeding 260°C depending on compound selection
- High pressure Kalrez® FFKM compounds offer strong compression set resistance for long-term sealing reliability
- These materials resist swelling, degradation, and chemical attack in aggressive fluid environments
- Kalrez® FFKM sealing systems are commonly used with backup rings to improve extrusion resistance under extreme pressure
Limitations of High Pressure Kalrez® FFKM Perfluoroelastomer
- Kalrez® FFKM materials have a significantly higher cost compared to FKM, HNBR, and other high pressure elastomers
- Lead times may vary depending on compound selection and custom geometry requirements
- Improper gland design or insufficient extrusion control can still lead to seal failure in extreme pressure environments
- Mechanical abrasion resistance may be lower than HNBR or polyurethane in certain dynamic applications
- Over-specifying FFKM materials in moderate pressure environments can increase cost without added performance benefit
Please consult a Canyon Components Engineer about your specific application and we will use our decades of experience to formulate a solution that fits your need.
Industrial Usage of High Pressure Kalrez® FFKM Perfluoroelastomer
High pressure Kalrez® FFKM O-rings, gaskets, and custom parts are used in applications where pressure, temperature, and chemical exposure create severe sealing challenges. These materials are widely specified in systems where extrusion resistance, chemical compatibility, and long-term reliability are essential. Selecting the right Kalrez® FFKM or Canrez® compound depends on pressure range, fluid chemistry, temperature, gland design, and decompression conditions.
Canyon Components provides engineering support to assist with material selection, backup ring recommendations, and high pressure sealing optimization. Our team can help evaluate application requirements and provide supporting documentation including Datasheets, TDS, Test Reports, MTR documentation, and MSDS or SDS resources to ensure reliable sealing performance in high pressure systems.
