Product description
Made from mirror-polished marine-grade 316 stainless steel, this garboard drain plug and deck filler is built to withstand saltwater exposure while maintaining strength and appearance. The polished finish improves corrosion resistance and offers a clean look on hulls and decks.
Machining and finishing focus on durability and safety: the alloy has high hardness to resist deformation, and edges are finely trimmed and smoothed to avoid snagging or cutting during handling or installation.
Installation is intended to be simple: the unit ships with the matching fasteners to secure the plate, enabling a quick and stable connection to your deck or hull fitting. It is designed for tool-assisted fitting and routine removal without a keyed cap.
Key dimensions — cover height: 69mm / 2.7 in; uncovered height: 55mm / 2.2 in; nozzle inner diameter: 17.5mm / 0.7 in; face diameter: 48mm / 1.9 in; outer ring diameter: 25mm / 1 in; hole spacing: 33mm / 1.3 in. These measurements help confirm compatibility with existing holes and recesses.
Intended uses include marine boats, yachts and caravans as a gas/fuel deck fill or garboard drain plug. Package contents: 1 PCS boat gas fuel deck fill/filler with keyless cap (1"), plus the supplied mounting hardware.
Pros
- Marine-grade 316 stainless with polished finish
- Supplied mounting hardware for quick fitting
- Clear dimensional specs for compatibility checks
Cons
- Some units reported missing the sealing O-ring
- May require extra sealant for a perfect watertight fit
- Fit depends on matching hole dimensions precisely
VerdictA robust stainless steel garboard drain plug and deck fuel/fill cap that offers corrosion resistance and neat mirror polish. It arrives as a single keyless-cap unit with the mounting hardware and suits 1" applications. Installation is straightforward for most vessels, though buyers should check that the included seal is present and confirm hole dimensions before fitting.

Leaked without seal
Arrived lacking the O-ring shown; when I added water it leaked from the shaft.
