Perko 2" Pipe To Hose Adapter Straight Bronze MADE IN THE USA

The Perko 2" Pipe to Hose Adapter Straight Bronze is a precision-engineered marine plumbing component designed for reliable fluid transfer in demanding saltwater and freshwater environments. Cast from marine-grade bronze, this 2-inch straight adapter connects standard 2-inch NPT pipe threads to 2-inch hose barb configurations, making it essential equipment for vessel cooling systems, raw water intakes, bilge applications, and fuel transfer lines aboard commercial and recreational watercraft.

The adapter features a precision-machined hose barb that provides secure grip on marine hose without requiring oversized clamps, reducing installation labor and minimizing vibration-induced leaks in engine compartments. The cast hex design accommodates standard wrenches for easier installation and removal during maintenance—a critical advantage when working in confined spaces aboard vessels. Bronze construction resists corrosion from saltwater immersion and extends service life significantly compared to ferrous alternatives, particularly in applications where cathodic protection systems are not present. The overall length of 2-5/8 inches fits standard through-hull fittings and manifold configurations found across marine propulsion systems and auxiliary equipment.

This adapter is specified by marine mechanics and vessel engineers for retrofit and replacement work where original equipment connections use NPT pipe thread to hose barb transitions. The straight configuration (as opposed to angled variants) simplifies plumbing layouts and reduces turbulence in circulation lines. Built to perform under sustained temperature cycling and pressure fluctuations common to marine duty, the Perko 2" adapter is manufactured in the USA and carries the reliability reputation of Perko's marine hardware line, trusted across fishing vessels, patrol boats, and commercial workboats for over 50 years.
