Fischer & Plath CU Copper Seal Washer

The Fischer & Plath CU Copper Seal Washer line gives you copper sealing washers (crush washers) for drain plugs, fittings, and other bolted connections where a leak-free joint matters. Fischer & Plath is a German sealing specialist. Each washer is made from copper, a soft metal that seals well and resists corrosion.

Key Features:

• Copper construction: Copper is soft enough to crush and conform to the mating surfaces, and it resists corrosion.
• Compressible sealing design: The washer compresses as the fastener is tightened. It spreads clamping force evenly and helps stop oil and fluid leaks.
• Common uses: Engine oil drain plugs, transmission drain plugs, and similar hydraulic or fluid-system fasteners.
• European sealing expertise: Fischer & Plath has supplied metallic gaskets, seals, shims, and precision stamped parts for decades.

Replace the washer each time you remove the plug or fitting. A compressed copper washer won't reseal as well a second time. A new washer gives you a more reliable seal after every oil or fluid change.
