Copper Washers

Copper Washers

Copper washers are designed to create a tight, reliable seal in threaded connections. The soft metal compresses under pressure, helping to prevent leaks in applications involving fluids or gases. Often referred to as sealing or crush washers, they are commonly used where a secure, leak-free joint is required.

Widely used in automotive, plumbing, and hydraulic systems, copper washers are ideal for applications such as sump plugs, fuel systems, and pipe fittings. Their ability to deform slightly under load ensures a consistent seal, even on uneven surfaces.
