FKM Fluororubber O-Rings

This product also offers excellent high-temperature resistance, with a long-term operating temperature of up to 200°C or higher, and is resistant to fuel oil, lubricating oil, and aromatic hydrocarbon solvents. It has a low compression set rate and maintains good rebound and sealing performance even after long-term compression. Inner diameter, cord diameter, and hardness grade can be customized according to customer equipment interface drawings.

FKM O-Rings are commonly used for flange sealing in chemical reactors and delivery pipelines, and are also widely used in automotive engine fuel injection systems, turbocharger piping, and other high-temperature, oil-resistant positions, making them suitable for chemical equipment manufacturers and automotive parts suppliers who need to cope with harsh media environments and extend equipment maintenance cycles.

Fluororubber raw material is relatively costly and is generally used in critical positions with extremely high sealing reliability requirements and high replacement costs. We can provide material inspection reports and chemical-media resistance test data to help customers assess material suitability during the selection stage.
