3/4″ Thru Hull Outlet SS | Marine-Grade Stainless Steel Discharge Fitting

The 3/4″ Thru Hull Outlet SS is a premium marine stainless steel thru hull fitting designed to deliver safe, efficient, and corrosion-resistant water discharge for boats, yachts, and offshore vessels. Manufactured from high-quality SS316 stainless steel, this thru hull outlet provides exceptional durability, strength, and resistance to rust, saltwater corrosion, chemicals, and UV exposure—making it ideal for demanding marine environments.

This 3/4 inch stainless steel thru hull outlet is engineered to handle medium-flow drainage and discharge systems such as bilge pump outlets, air-conditioning drainage, livewell systems, grey water discharge, freshwater overflow lines, and cooling system outlets. Its smooth internal bore ensures optimal water flow, reducing turbulence and back pressure that can strain pumps and hoses.

Unlike plastic or brass alternatives that degrade quickly in marine conditions, the SS316 stainless steel thru hull outlet maintains its integrity for years, even in continuous saltwater exposure. Whether installed above or below the waterline, this fitting provides a professional-grade, watertight solution that improves safety and system performance on any vessel.
