Perko 2" Thru-Hull Fitting w/Pipe Thread Bronze MADE IN THE USA

The Perko 2" Thru-Hull Fitting w/Pipe Thread Bronze is an essential marine plumbing component engineered for reliable through-hull installations on vessels of all sizes. This fitting serves as the primary interface between your boat's interior plumbing system and through-hull penetrations, making it indispensable for applications involving seawater intake, bilge discharge, and ventilation systems. Built to withstand the demanding marine environment, this American-made fixture ensures watertight integrity and long-term corrosion resistance in saltwater applications.

Constructed from marine-grade bronze, the Perko 2" thru-hull fitting resists galvanic corrosion and maintains structural integrity in continuous saltwater exposure—a critical advantage over lesser materials. The 2-inch nominal diameter accommodates standard hose connections and provides ample flow capacity for high-demand applications such as engine cooling systems and livewell circulation. The pipe thread design ensures secure, leak-free connections to compatible fittings and adapters, while the through-hull mounting configuration allows for clean deck or hull penetration with a flush, professional installation finish.

Boat builders, marine mechanics, and serious vessel owners rely on Perko thru-hull fittings for original equipment and retrofit applications. Installation typically involves drilling a 2-inch hole through the hull at the waterline or below, threading the fitting through, and securing it with stainless steel hardware and marine sealant for maximum water-tightness. Compatibility extends to standard 2-inch hose barbs, adapters, and ball valves commonly found in modern marine systems. When replacing aging or corroded fittings, this Made in USA component delivers the dependability required for safe, trouble-free boating.
