Viton (FKM) Rubber Seals for High-Temperature Automotive Applications
At Xingtai Guanghua Rubber Products Co., Ltd. , we specialize in manufacturing Viton (FKM) rubber seals designed for demanding automotive environments requiring high temperature resistance , chemical stability , and long-term sealing reliability .
FKM rubber, commonly known as Viton , is a premium fluoroelastomer widely used in automotive systems exposed to high heat , aggressive fluids , and harsh operating conditions . Compared with standard rubber materials, FKM offers superior resistance to engine oil , fuel , coolants , and chemical media .
Our automotive-grade Viton rubber materials are ideal for applications involving elevated temperatures (-20°C to +230°C), high pressures , and extended service life requirements . Choosing FKM rubber seals ensures:
- Excellent sealing performance at continuous temperatures up to 200°C with peaks to 230°C
- Outstanding resistance to oil, fuel, biodiesel, solvents, and aggressive chemicals
- Low compression set for long-term static and dynamic sealing integrity
- Extended service life in engine and powertrain systems with minimal maintenance
- Superior aging resistance and excellent retention of physical properties over time
FKM compounds are particularly critical for modern turbocharged engines , direct injection fuel systems , exhaust gas recirculation (EGR) components , and automatic transmission seals where conventional rubber materials would degrade rapidly.
We manufacture custom-molded FKM rubber seals including O-rings , valve stem seals , crankshaft seals , camshaft seals , fuel injector O-rings , and turbocharger gaskets widely used in engine sealing systems , fuel systems , turbocharger applications , hydraulic components , and other high-performance automotive assemblies.
All Viton products are formulated to meet automotive OEM specifications and undergo rigorous heat aging tests, fluid immersion testing, and compression set analysis to ensure reliable performance in extreme operating conditions throughout the vehicle's service life.

Frequently Asked Questions About Viton (FKM) Rubber Seals
Common questions about FKM rubber materials, high-temperature sealing, customization, and OEM supply.
What are Viton (FKM) rubber seals used for?
Viton (FKM) rubber seals are used in automotive applications requiring resistance to high temperatures, oil, fuel, and chemicals. Typical uses include engine seals, valve cover gaskets, O-rings, fuel system seals, and hydraulic components.
What temperature range can FKM rubber seals handle?
Automotive-grade FKM rubber seals typically operate within a temperature range of approximately -20°C to +200°C , with certain compounds capable of handling even higher temperatures.
How does FKM compare to NBR rubber?
FKM rubber offers superior heat and chemical resistance compared to NBR, making it suitable for high-temperature engine environments. NBR is more cost-effective for moderate temperature oil sealing applications.
Are FKM rubber seals resistant to fuel and chemicals?
Yes. Viton (FKM) rubber seals provide excellent resistance to fuels, oils, solvents, and a wide range of automotive chemicals.
Do you offer custom FKM rubber seals for OEM projects?
Yes. We offer OEM and ODM services for custom Viton rubber seals, including compound selection, hardness control, precision molding, and mold development.
What is the MOQ for Viton rubber seals?
MOQ depends on product type, size, and customization level. Standard FKM seals support bulk production, while custom-molded seals require project-based evaluation.
How do you ensure the quality of FKM rubber seals?
All FKM rubber seals undergo strict quality control, including material inspection, dimensional checks, hardness testing, and sealing performance validation to meet automotive standards.
