Function of Viton O-Rings Viton O-Rings are high-performance sealing components made from FKM (fluoroelastomer), designed to provide excellent resistance to heat, chemicals, oils, and fuels. Their main function is to prevent leakage of fluids or gases in both static and dynamic sealing applications. Key Functions and Benefits Superior Chemical Resistance: Viton O-Rings resist aggressive chemicals, acids, fuels, and solvents better than NBR or EPDM. High-Temperature Stability: Performs effectively in temperatures ranging from –20°C to +200°C, making them ideal for automotive, hydraulic, and industrial applications. Oil and Fuel Sealing: Excellent for sealing engine oils, fuels, and lubricants, ensuring long service life in harsh environments. Low Compression Set: Maintains sealing integrity even under high pressure and temperature cycles. Durability and Long Life: Reduces maintenance and replacement frequency due to superior wear resistance. Typical Applications Hydraulic and pneumatic systems Fuel handling systems Automotive engines and transmissions Chemical processing equipment Industrial valves and pumps
