Attwood Stainless Steel Thru-Hull Short Straight Barbed - 1-1/4" Inner Diameter

The Attwood Stainless Steel Thru-Hull Short Straight Barbed in 1-1/4" inner diameter is a marine-grade through-hull fitting engineered for reliable water intake and discharge applications on boats of all sizes. Whether you're running a raw water cooling system, bilge pump outlet, or transom drain, this fitting serves as the critical interface between your vessel's internal systems and the water outside the hull. Built by Attwood Marine—a name trusted across the industry for decades—this thru-hull fitting handles the demanding conditions that saltwater and freshwater boaters face daily.

Constructed from marine-grade stainless steel, this fitting resists corrosion far better than standard brass or zinc-plated alternatives, extending service life in both saltwater and brackish environments. The short straight barbed design provides secure connection to hose without requiring additional hose clamps on the interior side, reducing potential leak points and simplifying installation. The barbed end grips hose material firmly, while the thru-hull body threads securely through the hull with a tapered design that seals effectively against the hull material. Stainless steel's non-magnetic properties and superior resistance to galvanic corrosion make it the standard choice for serious boaters who refuse to compromise on reliability or longevity.

This 1-1/4" thru-hull fitting is ideal for anglers and cruisers operating everything from center consoles to offshore sportfishermen, where raw water cooling systems and circulation pumps demand dependable performance. Installation requires drilling a properly sized hole through the hull, sealing the exterior with marine bedding compound, and securing the fitting from the interior—a straightforward job that eliminates future leaks at critical system penetrations. Compatible with standard 1-1/4" marine hose, this fitting pairs perfectly with modern bilge systems, engine cooling loops, and livewell circulation setups. Attwood's proven engineering means you can focus on fishing and cruising, not worrying about failed through-hull fittings during your next trip offshore.
