FKM rubber, commonly known by the trade name Viton®, is a high-performance elastomer with excellent resistance to heat, chemicals, oils, fuels, and solvents. Here are some key features and benefits of FKM Viton expansion joints:

1. Chemical Resistance: FKM Viton rubber offers outstanding resistance to a wide range of chemicals, including acids, alkalis, fuels, oils, hydraulic fluids, and solvents. FKM expansion joints can withstand exposure to aggressive chemicals without degradation, making them suitable for use in chemical processing plants, refineries, and industrial applications where chemical resistance is critical.

2. High-Temperature Resistance: FKM Viton rubber has exceptional heat resistance, with continuous operating temperatures ranging from -20°C to +200°C (-4°F to +392°F) and intermittent temperatures up to +250°C (+482°F). FKM expansion joints maintain their properties and performance at elevated temperatures, making them suitable for high-temperature applications such as steam systems, exhaust systems, and process piping.

3. Oil and Fuel Resistance: FKM Viton rubber exhibits excellent resistance to oils, fuels, lubricants, and hydraulic fluids, making it ideal for applications involving exposure to petroleum products. FKM expansion joints can withstand contact with hydrocarbons without swelling, softening, or deteriorating, ensuring long-term reliability in oil and gas processing facilities, power generation plants, and automotive applications.

4. Low Gas Permeability: FKM Viton rubber has low gas permeability, making it suitable for sealing applications where resistance to gas or fluid migration is required. FKM expansion joints provide an effective barrier against gas leakage, preventing loss of pressure and contamination in pneumatic systems, hydraulic systems, and vacuum applications.

5. Weather Resistance: FKM Viton rubber offers excellent resistance to weathering, ozone, and UV radiation, making it suitable for outdoor applications where exposure to sunlight and weather is a concern. FKM expansion joints maintain their properties and performance over extended periods of outdoor exposure, making them suitable for use in marine, aerospace, and outdoor installations.

6. Mechanical Properties: FKM Viton rubber exhibits good mechanical properties, including resilience, flexibility, and tear resistance. FKM expansion joints can accommodate movement, vibration, and mechanical stress in piping systems while maintaining a tight seal and preventing leaks.

7. Longevity and Reliability: FKM Viton expansion joints are known for their durability, longevity, and reliability in demanding applications. FKM rubber retains its properties and performance over time, even in harsh operating conditions, contributing to the longevity and efficiency of piping systems.

Overall, FKM Viton expansion joints offer exceptional chemical resistance, high-temperature performance, and durability, making them suitable for a wide range of industrial, automotive, aerospace, and marine applications where reliability and longevity are essential
