The AG Long Brass Skin Fitting is a polished‑brass through‑hull (skin) connector with a 3/4″ male BSP thread on one side and a 19 mm hose barb on the other, ideal for secure fluid transfer applications on a boat. Its long body (~142 – 146 mm) allows deep mounting through thick hulls or tanks, providing reliable reach and sealing. Made from brass, it offers good corrosion resistance (above‑waterline use recommended; below‑waterline usage requires proper bonding due to dezincification risk). The flat head design ensures a streamlined external profile and helps reduce flow disruption. The fitting comes with a nut and washer to secure it tightly from the inside, establishing a watertight connection. Because of the barbed hose tail, two hose‑clamps are recommended to ensure a firm seal. Its polished finish gives a clean, professional look on the hull. Use cases include water intake/outlet, bilge discharge, or plumbing for manually or electrically pumped systems. According to manufacturer data, the thread is standard BSP, so it's compatible with BSP‑threaded sea‑cocks, valves, or other fittings.
