Description
Overview:
This 270‐piece Assorted Box of Copper Washers is a practical selection for sealing and load distribution on threaded joints in plumbing, automotive and light machinery. Made from solid copper, the washers compress slightly under torque to create a reliable seal and spread clamping forces evenly, helping to prevent leaks at unions, banjo fittings, hose tails and sump plugs. The set covers common imperial sizes (with metric equivalents) used across fuel, oil and water systems, making it useful in workshops, garages and site toolkits. Copper is naturally corrosion-resistant and suitable for regular service conditions. Supplied in an assorted box for straightforward storage and quick size selection, it supports fast replacements and first-time installations alike.
