Why Stock This Set

Copper washers prevent leaks at compression fittings without the risk of galvanic corrosion that steel washers can introduce. The thin profile (1–2mm) ensures proper seating on valve bodies and manifold ports, critical for maintaining system pressure in hydraulic and pneumatic equipment. By carrying a pre-sorted assortment, you reduce labor time picking individual sizes and position your shop as a single-stop source for fastening and sealing solutions.
