Perko 3/4" Pipe to Hose Adapter Straight Bronze MADE IN THE USA

The Perko 3/4" Pipe to Hose Adapter Straight Bronze is a marine-grade plumbing fitting engineered for applications requiring reliable fluid transfer between threaded pipe and barbed hose connections. Cast in bronze—a corrosion-resistant alloy ideal for freshwater and saltwater environments—this straight adapter combines material integrity with precision engineering to deliver leak-free performance in demanding marine systems, including through-hull fittings, bilge systems, and seawater cooling circuits.

The 3/4" pipe-to-hose connection accommodates standard marine hose diameters while the precision-machined hose barb creates a mechanized grip that resists vibration-induced loosening—critical in high-vibration vessel environments. The cast hex design simplifies installation by providing an engagement point for wrenches, eliminating the need for specialized tools and reducing installation time during retrofits or maintenance. A 1-3/4" overall length keeps the adapter compact while providing adequate material thickness for structural integrity and long service life. Manufactured in the USA, this adapter meets the durability expectations of professional boat builders and experienced cruisers who depend on reliability at sea.

This adapter is specified by marine system designers and boat owners who require corrosion-resistant fittings that maintain performance in salt spray exposure. Bronze adapters are particularly valued in offshore fishing operations, liveaboard cruising systems, and commercial vessel applications where galvanic compatibility with other through-hull hardware and natural salt water immersion resistance are non-negotiable. The straight configuration—as opposed to angled variants—suits installations where space permits direct, in-line connections and where flow characteristics demand minimal pressure drop across the fitting.
