Kalrez® FFKM O-Rings for Extreme Low Temperature Sealing
Kalrez® FFKM O-rings for extreme low temperature sealing are engineered for applications operating below -15°F where maintaining sealing force, elasticity, and dimensional stability becomes challenging. While perfluoroelastomers are primarily known for high temperature performance, specialized Kalrez® FFKM compounds are formulated to extend low temperature capability for critical applications that also require strong chemical resistance. These O-rings, gaskets, and custom parts are used in environments where both chemical exposure and low temperature conditions must be managed without seal failure.
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 low temperature performance, TR-10 behavior, and application requirements to ensure reliable sealing under challenging thermal conditions.
Common names include: Low temperature FFKM, perfluoroelastomer O-rings, cryogenic-capable elastomer seals
Trade names include: Kalrez®, Canrez®, Chemraz®, Parofluor®

Features of Kalrez® FFKM O-Rings for Extreme Low Temperature Sealing
- Kalrez® FFKM O-rings can be formulated for low temperature sealing below -15°F while maintaining chemical resistance
- Kalrez® FFKM O-rings provide excellent chemical resistance across aggressive fluids even in low temperature environments
- Low compression set characteristics help maintain sealing force after thermal cycling between low and high temperatures
- Kalrez® FFKM materials offer low outgassing and stable performance in vacuum and high purity applications
Limitations of Kalrez® FFKM O-Rings for Extreme Low Temperature Sealing
- FFKM materials have inherent limitations at low temperatures compared to silicone or fluorosilicone elastomers
- Standard Kalrez® compounds typically become less flexible below approximately -15°F, requiring specialized formulations
- Material stiffness increases as temperature decreases, which can reduce sealing effectiveness under low pressure conditions
- Cost is significantly higher than elastomers specifically optimized for low temperature performance
- Careful design considerations such as increased squeeze or alternative seal geometries may be required
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 Low Temperature Sealing
Kalrez® FFKM O-rings are used in applications where low temperature performance must be combined with chemical resistance and reliability. These O-rings are typically selected when standard low temperature elastomers cannot withstand the process media. Selecting the right Kalrez® FFKM or Canrez® compound depends on minimum temperature requirements, chemical exposure, pressure conditions, and seal design.
Canyon Components provides engineering support to assist with compound selection, TR-10 evaluation, 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 performance in low temperature environments.
