The Sea Dog 5200211 is a replacement plug and gasket pair designed to service Sea Dog 520010 and 520020 series 1" UV-resistant nylon drain plugs. Sold as a pair, this kit lets you restore a watertight seal on worn or damaged drain plugs without replacing the full fitting.
Parts Desk Insights
Best suited for boats where the drain plug body and receiver are still in good condition but the plug or gasket has cracked, swollen, or lost its seal — common after extended UV exposure or seasonal freeze-thaw cycles. Replacing the plug and gasket is a quick, low-cost fix before a leaking drain becomes a bigger problem. This pair is compatible with both the black and white versions of the Sea Dog 1" drain plug:
- Sea Dog Line 1" UV-Resistant Nylon Drain Plug with Gasket – Black (354-520010)
- Sea Dog Line 1" UV-Resistant Nylon Drain Plug with Gasket – White (354-5200101)
