Copper Washers
Copper Washers are high-quality sealing washers designed to provide reliable, leak-tight sealing in threaded hydraulic, pneumatic, fuel, oil, water, and industrial piping systems. Manufactured from premium-grade copper, these washers offer excellent resistance to high pressure, elevated temperatures, and corrosion while maintaining outstanding sealing performance. Their soft, malleable structure allows them to deform under tightening pressure, creating an effective metal-to-metal seal that prevents leaks in demanding applications. Copper washers are widely used in hydraulic equipment, fuel systems, engines, compressors, pumps, automotive, agricultural machinery, construction equipment, and general industrial installations.
Customers may also search for these products using the following names: copper sealing washer, copper washer, crush washer, seal washer, copper gasket washer, hydraulic copper washer, fuel injector washer, banjo bolt washer, copper ring gasket, thread sealing washer, metal sealing washer, oil drain plug washer, high-pressure sealing washer, annealed copper washer, flat copper washer, industrial sealing washer, pipe sealing washer, thread washer, copper sealing ring, hydraulic seal ring, copper gasket, and copper crush gasket.
Copper Washers are available in a wide range of internal and external diameters, thicknesses, and metric or imperial sizes, making them suitable for low-, medium-, and high-pressure applications. Their excellent thermal conductivity, corrosion resistance, and long service life make them one of the most widely used sealing solutions for threaded connections.
You can order these products from POLBERIS, where you will find a comprehensive selection of premium-quality copper washers, sealing products, hydraulic fittings, valves, and industrial piping components at competitive prices.
