FKM O-Rings (Viton® O-Rings)
FKM O-Rings for high temperature and chemical-resistant sealing applications, widely used in automotive, chemical, and oil systems. Available in standard and custom sizes with OEM manufacturing support.
Product overview
Product details
FKM (fluoroelastomer) is a high-performance sealing material designed for environments where standard elastomers fail due to heat, chemicals, or aggressive media. FKM O-Rings offer excellent performance in applications involving high temperatures, aggressive chemicals, fuels, and oils, ensuring long-term sealing reliability.
They are widely used in industries requiring high reliability and resistance to harsh conditions, including automotive, chemical processing, and oil systems.
Key Features
- Excellent high temperature resistance up to 200°C continuous (250°C short-term)
- Superior chemical and corrosion resistance against oils, fuels, and solvents
- Low compression set for long-term sealing stability
- Suitable for both static and dynamic sealing applications
- Long service life under extreme operating conditions
