Perko 1-1/8" Thru-Hull Fitting f/ Hose Plastic MADE IN THE USA

The Perko 1-1/8" Thru-Hull Fitting for Hose in plastic construction is a marine-grade through-hull fitting designed for seawater systems, bilge pumps, and raw-water cooling applications on boats. Made in the USA, this fitting provides a reliable connection point for 1-1/8-inch hose diameters and is engineered to withstand the corrosive salt-water environment where through-hull penetrations are critical to vessel safety and functionality.

The white molded plastic construction resists galvanic corrosion that can compromise metal through-hull fittings in saltwater applications. Its broad 2-1/4-inch outer diameter flange distributes load across the hull and reduces stress concentration at the penetration point. The fitting accommodates hull thicknesses up to 1-1/2 inches with a corresponding 1-1/2-inch mounting hole diameter, making it compatible with a wide range of vessel construction standards. At 0.1 pounds, the lightweight design adds minimal weight while maintaining the rigidity needed for constant pressure and temperature cycling in marine systems.

This Perko model (0328DP6A) is ideal for anglers, cruising sailors, and offshore fishing enthusiasts who need durable through-hull fittings that won't degrade in harsh marine environments. Whether you're upgrading a livewell system, replacing a corroded raw-water intake, or installing a new bilge or dewatering line, plastic through-hull fittings like this one provide years of trouble-free service when properly installed with appropriate sealing compounds and backing plates.

Perko through-hull fittings are engineered to the standards expected in marine equipment, where failure at a hull penetration can lead to serious consequences. This USA-made fitting reflects decades of marine hardware reliability and is a core component for any boater prioritizing vessel integrity and system longevity.
