Description
Overview:
This leather sealing washer is a robust, flexible ring used to create a tight seal between flat mating faces in pipework, tanks, housings and covers. Made from high‐quality natural leather, it compresses to fill small surface imperfections and helps prevent leaks of water and light oils. With an overall diameter of 4 inches (approx. 101.6 mm / 10.16 cm), it suits larger unions and flanges found across plumbing, automotive and industrial setups, as well as on construction and garden machinery. The smooth, dense leather faces provide reliable sealing without excessive torque. Identified by MPN 830 400, this washer is a practical choice for maintenance, repair and assembly tasks where a traditional, conformable gasket material is preferred.
