Sea-Dog Chrome-Plated Brass Washdown Water Outlet — with Cap & Chain
A permanent, good-looking deck outlet for connecting a garden hose to your onboard freshwater system for washdown use. The Sea-Dog 512120 mounts through the hull or deck and provides a standard male garden hose connector — so you can plug in any standard hose for rinsing down the deck, cleaning gear, or flushing out the anchor locker. The chrome-plated brass construction is corrosion-resistant and polished, and the included watertight cap with retaining chain keeps the fitting sealed and protected when not in use. Note: a separate ball or gate valve is required to control water flow at this fitting.

Parts Desk Insights
The 512120 is the outlet counterpart to the Sea-Dog 512110 Fresh Water Inlet — together they give you a complete shore water in / washdown out setup using the same chrome-plated brass hardware family. The outlet fitting itself has no built-in valve, so you’ll need a ball or gate valve inline to control flow; factor that into your installation plan. For a washdown fitting with a built-in shut-off, the T-H Marine WDV1DP Washdown Deck Fitting with Shut-Off Valve is a plastic alternative that handles flow control at the fitting. To protect your onboard plumbing from shore water pressure, pair the inlet with a pressure regulator: the SHURflo 65 PSI Wall-Mount Pressure Regulator or Jabsco Chrome Flush-Mount Pressure Regulator are both compatible options.
