StopTech BBK Copper Crush Washer

This listing is for a single copper crush washer from StopTech. It's designed to be used with StopTech Big Brake Kits (BBK) and is specifically intended for banjo bolt fittings. This washer helps create a solid seal when tightening the banjo bolt, preventing leaks of brake fluid.

Copper crush washers are a popular choice for brake line connections because copper is a soft metal that deforms easily to fill any imperfections in the mating surfaces of the banjo bolt and the brake line fitting. This makes for a reliable seal that can withstand the high pressures found in a braking system. When you're installing or servicing your Big Brake Kit, using a fresh crush washer like this one is a good practice to ensure a leak-free connection.
