Whitecap Industries 3/4 Inch Thru-Hull Fitting with Barb, 316 Stainless Steel and Plastic, Packaged

The Whitecap Industries S-3801C is a packaged 3/4 inch thru-hull fitting with barb, built from 316 stainless steel and plastic components. Thru-hull fittings like this one are installed through the hull below or near the waterline to create a through-hull passage for hose connections, commonly used for livewell intakes, washdown pumps, bilge discharge, and other onboard plumbing runs that need to draw water from or discharge water to the outside of the boat. The 316 stainless steel construction resists corrosion in both saltwater and freshwater environments, while the barbed fitting end is designed to accept 3/4 inch hose and hold it securely with a hose clamp. The plastic component works alongside the stainless steel body as part of the packaged assembly. This part comes packaged as a complete unit, so boat owners have what is needed for a single thru-hull installation without having to source additional pieces separately. It is a straightforward, functional fitting suited to replacement of a worn or corroded thru-hull, or for adding a new plumbing through-hull point during a boat build or refit.
