Stainless capped resin 15 degree thru hull 1 1/2"

Product Description

Upgrade your boat's plumbing system with our fiberglass reinforced resin thru hull fitting, engineered to outperform traditional stainless steel fittings while significantly reducing weight and cost. Designed specifically for saltwater environments, this 15-degree angled thru hull fitting delivers exceptional corrosion resistance, durability, and long-lasting marine performance.

Crafted with marine-grade fiberglass reinforced resin, it withstands the harshest saltwater conditions, while the polished 304 stainless steel cap — ultrasonically welded to the outer flange — provides enhanced protection against sun and salt damage. This innovative design addresses the common weaknesses found in standard plastic thru hull fittings, offering boat owners a sleek, professional finish with increased longevity.

Compatibility & Installation Made Easy

Our thru hull fitting features a 1-1/2" ID hose barb compatible with most marine hoses and includes extra-long threads to fit transoms up to 3-5/8" thick — making it ideal for a wide variety of boat configurations. The included stainless steel mounting nut ensures a secure, hassle-free installation. Perfect for both new builds and retrofits, this fitting is widely used by boat builders who value lightweight, durable, and reliable marine hardware.
