Barton Marine Drain Plug and Socket - White 15mm (19/32") Bore

The Barton Marine Drain Plug and Socket in white with a 15mm (19/32") bore is an essential through-hull fitting for any boat owner serious about routine maintenance and water management. Whether you're running a center console, cabin cruiser, or utility vessel, this drain plug assembly handles bilge water removal, washdown drainage, and routine hull inspections with reliable simplicity. After years on the water, experienced boaters know that proper drainage prevents soft rot, mold, and structural decay—making quality through-hull fittings non-negotiable for boat longevity.

Engineered by Barton Marine, this drain plug system combines a threaded socket design with a matching plug to create a watertight seal when closed and smooth drainage when open. The 15mm bore (19/32" equivalent) is sized for moderate water flow while remaining compact enough for tight installation spaces common in bilge areas, engine compartments, and transom wells. The white finish resists corrosion and UV degradation in saltwater and freshwater environments, ensuring years of fade-free performance. The plug-and-socket pairing allows for quick removal and reinstallation without special tools, critical when you need to pump out accumulated bilge water during routine haul-outs or storm preparation.

This fitting suits recreational boaters, fishing enthusiasts, and commercial operators who demand dependable through-hull hardware. Installation requires a simple hole-saw cut to 15mm diameter; the socket secures from inside the hull with standard fasteners, while the plug seats flush from the exterior. Verify your hull material and thickness before drilling, and always apply marine sealant around the socket flange to prevent water intrusion. Compatible with fiberglass, aluminum, and wooden hulls when properly sealed, this Barton Marine drain plug becomes invisible maintenance that protects your investment for seasons to come.
