GROCO 1-1/4" Bronze Combo Scoop Thru-Hull w/Nut

The GROCO 1-1/4" Bronze Combo Scoop Thru-Hull with Nut is a heavy-duty marine intake fitting designed for raw water circulation systems on boats ranging from mid-size cruisers to commercial vessels. Reliable through-hull fittings are essential for any serious boater, as they manage the continuous intake demands of engine cooling, washdown systems, and live wells.

Constructed from marine-grade bronze, this fitting is designed to resist galvanic corrosion and maintain structural integrity in harsh saltwater conditions. The 1-1/4" size accommodates moderate to high flow rates typical of raw water systems serving engine heat exchangers, air conditioning units, or hydraulic cooling loops. Its combo scoop design includes a strainer basket that prevents debris from clogging downstream components.

This thru-hull fitting is ideal for retrofit installations or new builds on displacement hulls, trawlers, and motor yachts where raw water draw is constant. The included nut ensures a secure, watertight seal against the hull, making it a reliable choice for boat owners committed to system reliability and corrosion resistance in both saltwater and freshwater environments.
