Perko 1-1/2" Seacock Ball Valve Bronze MADE IN THE USA

The Perko 1-1/2" Seacock Ball Valve Bronze (Model 0805008PLB) is a marine through-hull seacock engineered for demanding saltwater applications where reliability below the waterline is non-negotiable. Cast from bronzefor superior corrosion resistance in salt environments, this ball valve is manufactured in the USA and designed to integrate seamlessly with extra-long, scoop, or flush-type through-hull fittings commonly found on cruising sailboats, fishing vessels, and cabin cruisers.

The 1-1/2-inch pipe size accommodates moderate flow rates for through-hull applications including raw-water cooling systems, bilge discharge, or head installations. The 5-1/2-inch flange diameter provides a secure mounting surface against the hull, while the 4-1/2-inch overall height accounts for both the valve body and integrated hose adapter—critical dimensions for tight locker and through-hull configurations. The bronze construction resists galvanic corrosion better than ferrous metals and outlasts plastic alternatives in high-UV, high-salinity environments. Weighing 6.75 pounds, the valve's substantial construction ensures the internal ball mechanism stays sealed under thermal cycling and pressure variations typical of extended cruising or commercial fishing operations.

This seacock is purpose-built for serious boaters—weekend anglers installing new through-hulls, liveaboard cruisers replacing worn valves, and fishing boat operators managing raw-water systems. It solves the corrosion and failure risk that comes with inadequate valve selection in saltwater duty. Perko's marine-grade construction and USA manufacturing mean parts availability and design proven across decades of offshore service.

Marine through-hull valves are critical safety components; seacock failure can lead to water ingress and vessel loss. Bronze ball valves like this represent the industry standard for through-hull applications because the ball mechanism provides reliable shut-off without the corrosion susceptibility of gate valves or the maintenance demands of tapered plugs. The 1-1/2-inch size fits mid-range through-hulls, making this valve a common retrofit choice for boats with multiple through-hull systems.
