Whitecap Industries 1-1/2 Inch 316 Stainless Steel and Plastic Thru-Hull Fitting with Hose Barb

This Whitecap Industries thru-hull fitting provides a through-hull connection point for routing hose below the waterline or through a boat's hull, such as for a bilge pump discharge, livewell drain, washdown line, or raw-water intake run. It is built with a 316 stainless steel and plastic construction, combining a corrosion-resistant stainless flange with a plastic thru-hull body, and terminates in a hose barb fitting sized for 1-1/2 inch hose. The stainless steel component resists the corrosive effects of saltwater and marine spray at the point where the fitting passes through the hull, while the plastic thru-hull body keeps the part lightweight and helps control cost compared to an all-metal fitting.

The fitting mounts through a hole cut in the hull, with the flange seating against the exterior (or interior, depending on installation) surface and the hose barb accepting hose secured with a hose clamp. It is sold packaged for retail. At 0.3 pounds, it is a lightweight, low-profile component suited to smaller-diameter through-hull plumbing runs on recreational boats.
