FAQ
  • What are copper crush washers used for?

    Copper crush washers are designed to create a reliable, leak-free seal between fittings and mating surfaces in fluid systems. They are commonly used in brake, clutch, fuel, oil, and coolant applications to ensure secure connections.

  • What sizes are available for these washers?

    We offer copper crush washers in the following internal diameters:

    • 6mm (M6)
    • 8mm (M8)
    • 10mm (M10, 3/8" UNF, 1/8" BSP)
    • 11mm (7/16", AN4)
    • 12mm (M12)
    • 14mm (M14, AN6)

    This range ensures compatibility with various fittings and systems.

  • Are these washers compatible with your custom braided hoses?

    Yes, our copper crush washers are fully compatible with our range of custom braided hoses, including those used for brake, clutch, fuel, oil, and coolant applications. They ensure a secure, leak-free connection in high-performance environments.

  • How do I install these copper crush washers?

    Installation is straightforward: place the crush washer between the fitting and the mating surface, then tighten the fitting to the manufacturer's torque specification. The washer will deform slightly to create a tight seal. Ensure all connections are tight and leak-free before pressurising the system.

  • Are these washers reusable?

    No, copper crush washers are designed for single-use applications. Once compressed, they should be replaced to maintain a proper seal and prevent leaks.
