3/8″ Thru Hull Outlet SS | Marine-Grade Stainless Steel Discharge Fitting

The 3/8″ Thru Hull Outlet SS is a compact yet highly durable marine-grade stainless steel thru hull fitting designed for safe and efficient water discharge in boats, yachts, and industrial marine systems. Manufactured from premium SS316 stainless steel, this thru hull outlet offers superior corrosion resistance, long service life, and reliable performance even in the harshest saltwater environments.

Small in size but critical in function, this 3/8 inch stainless steel thru hull outlet is ideal for low-flow discharge lines such as air-conditioning drains, condensation outlets, livewell overflow lines, freshwater system relief lines, and small bilge discharge hoses. Its smooth internal bore ensures consistent flow, prevents clogging, and reduces pressure buildup within your system.

Unlike plastic or brass fittings that can crack, warp, or corrode over time, this SS316 stainless steel thru hull outlet is built to handle continuous exposure to saltwater, chemicals, heat, and vibration. Whether installed above or below the waterline, it provides a secure, watertight connection that protects your vessel from leaks and system failures.
