Perko 1-1/8" Thru-Hull Fitting f/Hose Narrow Flange - Plastic

The Perko 1-1/8" Thru-Hull Fitting for Hose Narrow Flange in plastic is an essential through-hull component for anglers and boaters who rely on reliable water intake and discharge systems. Whether you're running a raw-water cooling system, livewell circulation, or transom-mounted equipment, this fitting bridges your boat's hull to exterior hose connections with proven durability. Perko has been the trusted name in marine hardware for decades, and this compact plastic design offers corrosion resistance and lightweight installation without sacrificing performance in saltwater or freshwater environments.

This thru-hull fitting accommodates 1-1/8" hose and features a narrow flange design that minimizes deck footprint—critical when space is tight around rod holders, cleats, and other hardware. The plastic construction resists galvanic corrosion and won't degrade in prolonged saltwater exposure, making it ideal for coastal fishing operations where traditional metal fittings fail prematurely. The mounting hole diameter of 1-5/16" allows installation through hulls up to 1-1/2" thick, while the molded white finish blends seamlessly with modern boat interiors and exterior finishes. Installation is straightforward: drill, insert, seal with marine sealant, and tighten—no special tools required.

Boaters upgrading livewell systems, adding bilge pumps, or replacing aging transom fittings will appreciate the reliability and affordability of this Perko component. The narrow flange works perfectly on center consoles, cuddy cabins, and larger offshore rigs where hull space is at a premium. When paired with quality marine hose and stainless-steel clamps, this fitting delivers years of leak-free service in demanding freshwater and saltwater applications. Always verify hull thickness and hose diameter before purchase to ensure proper fit and optimal performance.
