Attwood Stainless Steel Thru-Hull Standard Straight Barbed - 1-1/8" Inner Diameter

The Attwood Stainless Steel Thru-Hull Standard Straight Barbed - 1-1/8" Inner Diameter serves as a critical component for maintaining the integrity of a vessel's plumbing and drainage systems. Designed for boaters who demand longevity beyond what standard plastic fittings can offer, this hardware provides a reliable passage through the hull for bilge pumps or livewell overflows. Whether upgrading an existing offshore fishing rig or outfitting a new build, this fitting ensures a watertight seal and professional appearance. Its robust construction is specifically engineered to withstand the harsh conditions of both freshwater and saltwater environments.

Constructed from high-grade stainless steel, this thru-hull fitting features a polished finish that resists corrosion and maintains its luster over years of exposure. The 1-1/8" inner diameter is paired with a barbed tailpiece, which allows for a secure, slip-resistant connection to flexible marine hoses. Unlike nylon or plastic alternatives, the rugged stainless steel design prevents the brittleness and cracking often caused by UV exposure or mechanical stress. The straight configuration facilitates a direct flow path, minimizing resistance in drainage or intake applications.

This plumbing hardware is ideal for installation above the waterline, providing a sleek aesthetic that complements other stainless steel deck hardware. Installation requires a standard cutout, and the threaded body allows for a tight fit against the hull using a compatible nut and sealant. Owners of center consoles, cruisers, and performance boats will find this component essential for a permanent, "life of the boat" solution. For those looking to buy a replacement part or upgrade their current specifications, this Attwood fitting offers the durability required for serious maritime use.
