The 1″ Thru Hull Outlet SS is a premium-quality marine stainless steel thru hull fitting designed for safe, efficient, and long-lasting water discharge in boats, yachts, and commercial marine vessels. Manufactured from marine-grade SS316 stainless steel, this thru hull outlet delivers superior resistance to corrosion, rust, and electrolysis, making it ideal for harsh saltwater and industrial environments.
This 1 inch stainless steel thru hull outlet is engineered to provide smooth, high-efficiency water flow for essential onboard systems. It is widely used for bilge pump discharge, air-conditioning drainage, engine cooling outlets, livewell drains, deck wash outlets, and sink waste systems. The smooth internal bore reduces turbulence and back pressure, allowing pumps to operate more efficiently while extending the life of your hoses and equipment.
Unlike plastic or brass alternatives that crack, deform, or corrode over time, this SS316 thru hull outlet maintains its strength and appearance for years. It is suitable for installation above or below the waterline, offering peace of mind and professional-grade reliability.
