Sea-Dog Washdown Water Outlet 513120-1, 316 Stainless Steel, 1/2 Inch FIPT x 3/4 Inch Garden Hose Thread

The Sea-Dog Washdown Water Outlet (part number 513120-1) connects a standard garden hose to an onboard water system, giving boaters a dedicated washdown point for rinsing gear, decks, anchors, and fishing equipment. The outlet is machined from investment cast 316 stainless steel, a corrosion resistant alloy well suited to saltwater and marine environments where lesser metals would pit or rust over time.

The fitting uses a 1/2 inch FIPT (female iron pipe thread) connection on the plumbing side and a 3/4 inch MGHT (male garden hose thread) on the outlet side, so it accepts a standard male hose connector without adapters. Installation requires a separate ball or gate valve, sold separately, to regulate water flow to the outlet. The outlet mounts with a #8 flat head fastener and measures 2-3/4 inch by 1-11/16 inch by 2-3/16 inch by 1 inch across its mounting dimensions.

Sea-Dog also offers a replacement cap (512129-1) for this outlet as a separate accessory, useful for boaters who want a spare or replacement closure without buying the full assembly.
