Key Benefits

  • High Pressure Resistance – Effectively seals under high-pressure conditions, making them ideal for hydraulic and pneumatic systems.
  • Reliable Metal-to-Metal Sealing – Combines a metal washer with a rubber sealing element for strong, secure sealing between flat surfaces.
  • Reusable and Easy to Install – Simple to fit and often reusable depending on application and wear.
  • Wide Temperature Range – Performs well in extreme temperatures due to the resilient elastomer material.
  • Leak Prevention – Provides a secure seal that minimizes the risk of fluid leakage, enhancing system reliability.

    • Can replace copper washers in high-pressure systems.
    • Resistant to high pressure and temperature variations.
    • Not suitable for highly dynamic sealing applications (e.g., rotating shafts).
    • Elastomer compatibility with fluid must be verified to avoid degradation.
    • Excessive over-tightening may damage the rubber seal.
