Introduction
A copper washer is a precision sealing component made from high-purity copper, widely used in automotive, hydraulic, plumbing, and industrial applications. Thanks to copper’s natural softness and malleability, the washer deforms slightly under pressure, creating a tight, reliable seal that effectively prevents leaks of oil, fuel, water, or gas. Copper washers offer excellent thermal and electrical conductivity, making them suitable for high-temperature environments such as engines, exhaust systems, and braking systems. They also provide strong corrosion resistance, even in harsh operating conditions, ensuring long service life and consistent performance. Available in various inner diameters, outer diameters, and thicknesses, copper washers can be used for sealing bolts, banjo fittings, sensors, and pipe connections where durability and dependable sealing are critical.
