Collection: Copper Washers
Copper washers are soft metal washers that crush slightly when tightened, sealing the joint against oil, fuel, water and brake fluid. They are used on sump plugs, banjo bolts, injectors and hydraulic fittings, and conduct electricity well.
Our range runs from M4 to M45 in thicknesses from 0.8 mm to 5.5 mm.
A crushed sealing washer seals best when replaced. See also Aluminium Washers and Dowty Washers.
