Description
8mm ID copper sealing washer for an 8mm banjo bolt. Fits under the head of the bolt to seal the joint between it and the caliper, wheel cylinder, or hose end. Annealed copper deforms under torque to form the seal; once compressed it work-hardens and won’t reseal reliably if reused, so replace both washers (one on each side of the banjo fitting) whenever a banjo bolt is removed.
