Sea-Dog Line Water Outlets & Washdown Spigots for Marine Plumbing

When it comes to keeping a vessel clean and well-maintained on the water, reliable plumbing fittings are essential. Sea-Dog Line brings over a century of marine hardware expertise to its Water Outlets & Washdown Spigots lineup, offering boaters practical, durable solutions for connecting onboard freshwater systems to standard garden hoses and dock-side water supplies.

Purpose-Built Marine Plumbing Fittings

Sea-Dog Line offers two core fitting types in this category, each engineered to solve a specific marine plumbing need:

• Washdown Water Outlet: This fitting allows a garden hose to be hooked up to the onboard water system for use as a washdown system. It features a standard male hose connector and requires a separate ball or gate valve to regulate water flow, with a pipe size of 1/2" FIPT x 3/4" MGHT.
• Fresh Water Inlet: Designed to provide a fresh water hookup to a pressurized water system while moored, this fitting features a standard female swivel hose connector and comes complete with a black plastic, watertight plug when not connected to shore water. Pipe size is 1/2" FIPT x 3/4" FGHT.

316 Stainless Steel Construction for Harsh Conditions

Crafted from high-quality, investment cast 316 stainless steel, Sea-Dog's washdown water outlet is built to withstand the harsh marine environment. This robust material is exceptionally resistant to corrosion, salt spray, and UV rays, ensuring long-lasting performance and reliable operation season after season. For boaters who spend time in saltwater environments, the choice of 316 stainless steel over lower grades is a meaningful distinction that translates directly to longevity.

Simple Installation, Standard Compatibility

The washdown outlet features a 1/2-inch FIPT inlet for connection to the boat's plumbing, and a 3/4-inch MGHT outlet for easy attachment to standard garden hoses — compatibility that ensures hassle-free installation and efficient water flow for effective cleaning. This standardized sizing means no adapters or special tools are required for most installations.

A Brand Boaters Have Trusted for Generations

The Sea-Dog marine line is celebrating over 100 years as a supplier of quality marine parts for retail and OEM customers, and stocks more than 8 million parts in a 75,000 square foot warehouse in Washington state.
