Perko 1" Thru-Hull Fitting f/Hose Bronze MADE IN THE USA

The Perko 1" Thru-Hull Fitting for Hose in Bronze is a time-tested marine through-hull connector engineered for anglers, boaters, and vessel owners who demand reliability in demanding saltwater and freshwater environments. This cast bronze thru-hull fitting serves as a critical junction point for through-hull hose applications—bilge systems, raw water cooling lines, livewell plumbing, and other essential boat systems. Made in the USA by Perko, a manufacturer trusted for nearly a century in marine hardware, this fitting combines traditional bronze construction with precision engineering to resist corrosion and deliver decades of dependable service.

The 1" bore accommodates standard marine hose diameters, while the machined flange is grooved to securely retain bedding compound, ensuring a watertight seal that protects against leaks and galvanic corrosion. The threaded neck extends approximately 3/16 inch from the flange, providing a secure mounting point for through-hull installation where the flange sits flush against the hull exterior. Cast bronze construction naturally resists seawater corrosion better than steel or aluminum, making it ideal for saltwater vessels; optional chrome-plated brass variants are available for enhanced aesthetics. Regular and short-length versions accommodate different hull thicknesses and installation configurations, with this listing covering the standard regular-length design.

Experienced anglers and boaters upgrading or repairing through-hull systems will appreciate the precision fit and long service life this Perko fitting delivers. Installation works with 1" hose on either side of the hull—whether connecting a livewell, raw water intake, or bilge discharge line. Proper bedding with marine sealant compound (applied to the grooved flange) is essential for lasting performance. This made-in-USA fitting meets the expectations of vessel owners who prioritize corrosion resistance and reliability over the life of their boat.
