1-1/4″ Thru Hull Outlet SS | Marine-Grade Stainless Steel Discharge Fitting

The 1-1/4″ Thru Hull Outlet SS is a heavy-duty marine stainless steel thru hull fitting designed for reliable, high-flow water discharge in boats, yachts, and offshore vessels. Manufactured from premium SS316 stainless steel, this fitting offers superior resistance to corrosion, rust, saltwater, chemicals, and extreme marine conditions. It is the perfect solution for marine plumbing systems that require strong, safe, and long-lasting hull penetration.

This 1-1/4 inch stainless steel thru hull outlet is engineered to support higher flow rates, making it ideal for bilge pump discharge, engine cooling water outlets, air-conditioning drain lines, livewell systems, and grey water discharge systems. The smooth internal bore ensures fast, unrestricted water flow while minimizing back pressure that can damage pumps and hoses.

Unlike plastic or brass fittings that crack, corrode, or weaken over time, this SS316 thru hull outlet delivers long-term durability even when continuously exposed to saltwater. Whether installed above or below the waterline, this marine thru hull fitting ensures a secure, leak-proof, and professional-grade installation.
