Perko 1-1/2" Thru-Hull Fitting f/Hose Plastic MADE IN THE USA

The Perko 1-1/2" Thru-Hull Fitting for Hose Plastic is an essential component for any boat owner managing through-hull applications—from bilge systems and raw water intakes to drain lines and ventilation. After years on the water, you learn that reliable thru-hull fittings are non-negotiable; they're the silent guardians preventing leaks and system failures when you're miles from shore. This molded white plastic fitting is engineered to handle the demands of saltwater and freshwater environments, providing a corrosion-resistant alternative to metal fittings that can degrade in harsh marine conditions.

Featuring a broad flange design and molded white plastic construction, this Perko fitting accommodates 1-1/2" hose and mounts through a 1-7/8" hole, making it compatible with hulls up to 1-7/8" thick. The broad flange distributes clamping pressure evenly across the hull surface, reducing stress concentrations and preventing the cracking that can occur with standard flanges on fiberglass hulls. Made in the USA, this fitting meets the durability standards Perko has maintained for decades, ensuring the plastic resists UV degradation and maintains structural integrity through years of seasonal exposure and temperature cycling.

This fitting works best for cruising and fishing boats where weight savings and corrosion resistance outweigh the need for heavy-duty metal options. Installation is straightforward: drill the 1-7/8" mounting hole, slide the fitting through, and secure with the backing nut and gasket. Whether you're upgrading an older system or building a new installation, verify your hull thickness and hose size match the 1-1/2" specification before ordering. Perko thru-hull fittings are trusted by professional boat builders and weekend anglers alike for reliable, leak-free performance season after season.
