FFKM for Extreme Low Temperatures
Extreme low temperature environments present a unique challenge for sealing materials, often causing standard elastomers to become brittle, lose elasticity, and fail to maintain sealing force. FFKM (perfluoroelastomer) O-rings, gaskets, custom parts, and tubes designed for low temperature applications are engineered to retain flexibility, resilience, and sealing performance even in sub-zero and cryogenic conditions.
At Canyon Components, Canrez® FFKM low temperature compounds such as CP90BK20, CP90BK21, CP75BK91, and CP80BK78 are specifically formulated to extend the usable temperature range of FFKM into environments where traditional perfluoroelastomers would typically struggle. These compounds provide an excellent balance of low temperature flexibility, chemical resistance, and high temperature capability, making them ideal for applications that experience wide temperature swings.
Unlike standard FFKM materials, which are often limited at lower temperatures, Canrez® FFKM O-rings, gaskets, and custom parts are engineered to resist embrittlement and maintain sealing integrity in extreme cold. Compared to Kalrez® and Chemraz®, Canrez® offers strong performance, improved availability, and competitive pricing, making it a practical solution for demanding low temperature sealing applications. Canyon Components engineers can help evaluate your operating conditions and recommend the optimal compound and design for reliable sealing performance.
Common names include: FFKM, Perfluoroelastomer, Perfluorinated Rubber. Trade names: Canrez®, Kalrez®, Chemraz®, Simriz®, Parofluor®.

Limitations of Extreme Low Temperature FFKM O-Rings, Gaskets, & Custom Parts
- FFKM O-rings, gaskets, and custom parts generally have a higher upfront cost compared to materials like silicone or EPDM designed for low temperature use
- Extremely low temperature applications may require careful compound selection, as performance varies significantly between FFKM grades
- Low temperature sealing performance can be influenced by seal design, squeeze, and gland configuration, requiring proper engineering validation
- Lead times for certain competitor materials (Kalrez®, Chemraz®) can be longer, while Canrez® FFKM offers strong availability and faster turnaround
- In some cases, specialized solutions such as PTFE spring energized seals or encapsulated O-rings may be better suited for ultra-cryogenic conditions
