Engineered for Demanding Industrial Environments
FKM (Fluorocarbon) O-rings are the gold standard for sealing in harsh conditions. Known by the brand name Viton™, these elastomers offer unparalleled resistance to heat, oil, and chemicals.
Thermal Stability
Operates reliably from -20°C to +200°C, with intermittent resistance up to +230°C for extreme heat cycles.
Chemical Excellence
Superior resistance to fuels, mineral oils, hydraulic fluids, and many organic solvents and chemicals.
Durability & Aging
Exceptional resistance to ozone, oxidation, and UV weathering, ensuring long-term outdoor service life.

Frequently Asked Questions
What is the difference between FKM and Viton?
FKM is the ASTM designation for fluorocarbon rubber, while Viton™ is the brand name by Chemours. They refer to the same base material, though Viton™ often implies a specific high-quality standard of compounding.
Can FKM O-rings be used in steam applications?
Standard FKM has limited resistance to steam. For high-pressure steam or hot water applications, we recommend peroxide-cured FKM grades or EPDM materials for better longevity.
How do I choose between 70 and 90 Shore A hardness?
70 Shore A is the standard for most general sealing applications. 90 Shore A is significantly stiffer and is preferred for high-pressure environments to prevent the O-ring from extruding into the clearance gaps.
