Stainless capped resin straight thru hull 1 1/2"

Product Description

Upgrade your boat’s plumbing system with our premium Straight Thru Hull Fitting, designed to deliver outstanding durability and a sleek, polished look without the extra cost or weight of full stainless steel fittings. Trusted by saltwater boat builders and marine professionals, this fitting offers superior performance in challenging marine environments.

Crafted from tough fiberglass reinforced resin, the fitting resists corrosion, flexing, and damage from harsh saltwater conditions. The polished 304 stainless steel cap, ultrasonically welded to the flange, not only boosts your boat’s aesthetics but also protects against sun and salt damage—a common issue with traditional plastic fittings.

Designed with hose barbs to fit 1-1/2" ID marine sanitation hose, this fitting adapts to various boat configurations, providing versatility for your plumbing or sanitation system. A mounting nut is included for easy, secure installation, helping you save time on maintenance or upgrades.
