Marine Thru Hull Fittings For Boats


What Are Thru Hull Fittings?

A Thru Hull is a fitting designed to accept pipes, hoses, or valves to allow water to pass in or out of a vessel. This definition of Thru-Hulls is straight from the American Boat and Yacht Council. We carry thru hulls from Perko, Rule, Forespar, Groco, Wilcox-Crittenden, in molded plastic, stainless steel, and bronze. Products include deck plates, hose fittings, flanging tools, drain plugs, and more.
