What is Automotive accessories high pressure O-ring FKM VMQ
Material composition
FKM (fluororubber): Known for its excellent chemical resistance and high temperature resistance, suitable for a variety of automotive fluids and oils.
VMQ (silicone rubber): Provides good high temperature resistance and flexibility, and enhances the sealing effect of the O-ring.
Product features
- High pressure resistance: Able to withstand high pressure environments and maintain sealing performance.
- Temperature resistance: Suitable for a wide temperature range, typically from -60 °C to +200 °C.
- Chemical resistance: High resistance to oil, fuel, coolant, and other automotive fluids.
- Wear resistance: Surface treatment reduces friction and extends service life.
- High elasticity: Even after long-term use, it can quickly return to its original state.

Application of Automotive accessories high pressure O-ring FKM VMQ
- Engine seal: Used for engine oil seals, valve covers and other components to prevent oil leakage.
- Transmission seal: Ensure that the transmission oil does not leak and improve transmission efficiency.
- Hydraulic system seal: Used for hydraulic cylinders, pumps, valves and other components to ensure system pressure stability.
- Pneumatic system seals: used for pneumatic tools and equipment to ensure air tightness.
