Kalrez® FFKM O-Rings for Extreme Temperature Sealing
Kalrez® FFKM O-rings for extreme temperature sealing are engineered for applications requiring reliable performance across a wide thermal range from -20°C to 300°C. These perfluoroelastomer O-rings are designed to maintain sealing integrity in environments that combine high heat, aggressive chemicals, and demanding operating conditions. Kalrez® FFKM materials provide excellent resistance to thermal degradation, compression set, and chemical attack, making them ideal for O-rings, gaskets, and custom parts used in critical sealing systems.
Canyon Components supplies Kalrez® FFKM O-rings alongside Canrez® perfluoroelastomer alternatives, offering a competitively priced solution with fast lead times and extremely high quality. Our team supports compound selection based on temperature cycling, chemical exposure, and application requirements to ensure consistent sealing performance across extreme temperature ranges.

Features of Kalrez® FFKM O-Rings for Extreme Temperature Sealing
- Kalrez® FFKM O-rings provide reliable sealing performance across a wide temperature range from -20°C to 300°C
- FFKM materials maintain elasticity and sealing force at elevated temperatures while resisting thermal degradation
- Kalrez® FFKM O-rings offer excellent chemical resistance to aggressive fluids, acids, solvents, and hydrocarbons
- These O-rings exhibit low compression set, supporting long-term sealing reliability under thermal cycling conditions
- Kalrez® FFKM materials provide low outgassing and low extractables for vacuum and high purity applications
- Canrez® FFKM O-rings deliver comparable performance with competitive pricing and improved availability
Limitations of Kalrez® FFKM O-Rings for Extreme Temperature Sealing
- Kalrez® FFKM O-rings have a higher cost compared to FKM, EPDM, and other elastomer materials
- Low temperature flexibility is limited compared to silicone or specialized low temperature elastomers below -20°C
- Lead times may vary depending on compound availability and size requirements
- Mechanical properties such as abrasion resistance may be lower than HNBR or polyurethane in high-wear applications
- Over-specifying FFKM for applications that do not require extreme temperature performance can increase cost without added 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 Kalrez® FFKM O-Rings for Extreme Temperature Sealing
Kalrez® FFKM O-rings are used in applications where both high and low temperature extremes must be managed without compromising sealing performance. These O-rings are widely specified in systems exposed to thermal cycling, aggressive chemicals, and demanding operating conditions. Selecting the right Kalrez® FFKM or Canrez® compound depends on temperature range, chemical exposure, pressure, and seal design.
Canyon Components provides engineering support to assist with compound selection, thermal analysis, and 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 across extreme temperature environments.
