Whitecap C.P. Brass Sillcock 1-5/8" Base 3-3/16 Depth

The Whitecap C.P. Brass Sillcock 1-5/8" Base 3-3/16" Depth is a marine-grade through-hull fitting designed for freshwater and saltwater vessel applications. This deck-mounted fixture allows controlled water access for washdown systems, cooling lines, or galley use while preventing unwanted backflow when shut off. Anglers and boaters who spend extended time on the water understand the critical importance of reliable hardware.

Constructed from chromed brass (C.P.), this fixture resists salt spray and galvanic corrosion better than standard steel components. The 1-5/8" base diameter accommodates standard through-hull openings, while the 3-3/16" depth ensures proper installation through typical deck thicknesses without requiring extensive modification. The manual valve mechanism provides intuitive control—a simple quarter-turn operation engages or isolates the water flow.

This Whitecap sillcock is ideal for recreational fishing vessels, cruising sailboats, and utility craft where reliable freshwater supply or seawater access is essential. Installation requires a matching 1-5/8" diameter through-hull opening and basic fastening hardware, making it a straightforward project for most boat owners.
