Sea-Dog Sink Drain with Strainer 517526-1, Straight 2 Inch, Stainless Steel Body, 5/8 Inch Barb

The Sea-Dog Sink Drain with Strainer (517526-1) is a straight-style drain fitting built for 2 inch sink openings aboard boats, RVs, and other marine applications. It combines a stainless steel body with a zinc cap and nylon fittings, giving it the corrosion resistance needed for galley sinks and other wet environments while keeping the cap durable against repeated use. The drain includes a 5/8 inch barb on the underside, allowing a length of hose to be pushed on and clamped for a secure connection to a through-hull or drain line.

The strainer sits in the drain opening to catch debris before it reaches the plumbing, and the removable design makes it easy to lift out for cleaning. This straight configuration is intended for direct, in-line drainage where the fitting passes straight through the sink base rather than at an angle. It is packaged as a single unit, ready to install in any 2 inch sink cutout without additional adapters.
