A sealing washer is a small but essential hardware component used at threaded fastener points where a fluid-tight joint is required. Unlike a plain flat washer, it incorporates a sealing function — preventing oil, coolant, or other fluids from weeping past the threaded connection it sits under. In an outboard motor or water pump, even a minor fluid leak at a drain plug or bolt can lead to fluid loss, contamination, or corrosion damage over time. Replacing a worn or damaged sealing washer at each service interval is a straightforward step that maintains the integrity of the joint and keeps fluids where they belong.
