Kalrez® FFKM O-Rings
Kalrez® FFKM O-rings are high-performance sealing solutions designed for extreme environments where chemical resistance, temperature stability, and long-term reliability are critical. These perfluoroelastomer O-rings are widely used in industries such as semiconductor manufacturing, oil and gas, chemical processing, and pharmaceutical production where standard elastomers cannot withstand aggressive media or elevated temperatures. Kalrez® FFKM O-rings provide excellent resistance to a broad range of chemicals, including acids, solvents, fuels, and plasma environments, while maintaining sealing performance across wide temperature ranges.
Canyon Components supplies Kalrez® FFKM O-rings alongside Canrez® perfluoroelastomer alternatives, offering a competitively priced solution with fast lead times and extremely high quality. Whether you require standard AS568 sizes, metric O-rings, or custom molded geometries, our team supports material selection, sizing, and application-specific requirements to ensure optimal sealing performance.
Common names include: Perfluoroelastomer, FFKM O-rings, High Performance O-rings

Features of Kalrez® FFKM O-Rings
- Kalrez® FFKM O-rings exhibit low compression set, supporting long-term sealing reliability in static and dynamic applications
- FFKM O-rings provide low outgassing and low extractables, making them ideal for vacuum and high purity environments
Limitations of Kalrez® FFKM O-Rings
- Certain Kalrez® compounds may have extended lead times depending on size and availability
- Low temperature flexibility is limited compared to silicone or specialized low temperature elastomers
- FFKM materials may have lower abrasion resistance than HNBR or polyurethane in high-wear dynamic applications
- Over-specifying Kalrez® FFKM O-rings for moderate applications 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
Kalrez® FFKM O-rings are used in demanding sealing applications where chemical resistance, temperature stability, and long service life are essential. These O-rings are widely specified in critical systems where failure is not acceptable. Selecting the right Kalrez® FFKM or Canrez® compound depends on chemical exposure, temperature range, pressure, and application type.
Canyon Components provides engineering support to assist with compound selection, sizing, and seal design optimization. Our team can help evaluate performance requirements and provide supporting documentation including Datasheets, TDS, Test Reports, MTR documentation, and MSDS or SDS resources to ensure reliable sealing performance.
