Fit this gasket to hatch surrounds and cover fittings where a flexible bulb seal is required. When installing, ensure the mating surface is clean and dry, compress the gasket by about 10–20% for a reliable seal, and use a compatible marine adhesive if a permanent bond is preferred. For maintenance, rinse with fresh water, avoid petroleum-based solvents, and inspect seals annually for wear or compression set. See our Seals & Gaskets collection for matching parts and tools.
