Description
Overview:
These 14 x 20 x 2 mm compression washers are copper sealing rings designed to create a tight, leak‐resistant joint when clamped under a nut, bolt, or fitting. The 14 mm inner diameter suits M14 fixings and ports, while the 20 mm outer diameter provides a stable seating area; the 2 mm thickness offers reliable crush to form a gasket-like seal. Copper resists corrosion and conforms under load, making these washers a practical choice for plumbing, automotive, and machinery service work. Use them on banjo bolts, hose tails, compression fittings, sump plugs, and hydraulic or fuel connections found on construction plant, generators, compressors, and garden machinery. Supplied in a pack of 50 for workshop and site maintenance. Manufacturer Part Number: 915 505.
