1-1/2″ Thru Hull Outlet SS | Marine-Grade Stainless Steel Discharge Fitting

The 1-1/2″ Thru Hull Outlet SS is a premium marine stainless steel thru hull fitting engineered for high-flow, safe, and long-lasting water discharge in boats, yachts, and commercial marine vessels. Manufactured from marine-grade SS316 stainless steel, this fitting delivers outstanding corrosion resistance, strength, and durability even in harsh saltwater and industrial environments.

Designed for heavy-duty marine plumbing systems, this 1-1/2 inch stainless steel thru hull outlet is ideal for applications such as bilge pump discharge, engine cooling outlets, air-conditioning drains, grey water systems, livewell drains, and deck wash discharge lines. The smooth internal bore ensures maximum flow efficiency while reducing turbulence and back pressure that can damage pumps and hoses.

Unlike plastic or brass thru hull fittings that weaken or corrode over time, this SS316 stainless steel thru hull outlet is built for long-term safety and performance. Whether installed above or below the waterline, it provides a secure, watertight hull penetration that protects your vessel from leaks and structural damage.
