Description:

A solid copper sealing washer for use on Austin Healey brake hose connections. This washer sits between the brake hose fitting and the mating hydraulic component to create a fluid-tight seal under pressure.

Purpose & Installation Notes

  • Designed for use with banjo-style hose fittings where specified
  • Single-use item – replacement recommended whenever a hose is removed
  • Prevents brake fluid seepage under system pressure

Always inspect the mating faces for scoring or distortion before installation. Tighten to the correct torque specification for the brake hose fitting being used. Suitable for use with DOT 3, DOT 4, and DOT 5.1 brake fluids. Not intended for reuse once compressed.

FAQs

Is this washer used on all Big Healey brake hoses?

It is used where the brake hose incorporates a banjo-type fitting requiring a copper sealing washer. It is not required on flare-type rigid pipe unions that seal metal-to-metal.

Should the washer be replaced when fitting a new brake hose?

Yes. Copper washers deform to create a seal and should not be reused. Always fit new washers when installing or removing brake hoses.

Is one washer supplied or a pair?

This listing is for a single copper washer. Confirm the quantity required for the specific hose connection before ordering.

Is it compatible with silicone brake fluid?

Copper washers are compatible with conventional glycol-based fluids (DOT 3, 4, 5.1) and silicone-based DOT 5 fluid, provided the system components are suitable.
