BOLT MC Hardware Aluminum Crush Washers

BOLT MC Hardware aluminum crush washers, also called drain plug washers, compression washers or drain plug gaskets, are made to seal fluids at bolted connections. They suit oil drain plugs, coolant drain plugs, check bolts and other places where a bolt has to hold fluid in.

Key Features:

• Soft-tempered aluminum construction: the washer compresses as the bolt is tightened, so it conforms to the mating surface and seals.
• Fluid sealing: works for oil, coolant and similar fluid applications.
• Replaceable seal: OEMs generally recommend a fresh crush washer at each oil or coolant change, because the old washer is deformed by use.
• Versatile uses: good for drain plugs, check bolts and other fluid-retaining fasteners on motorcycles, powersports vehicles and other equipment.

A new crush washer at every fluid service helps prevent seepage and leaks at the drain plug. Choose the correct size for your plug from the available options.
