Stainless capped resin straight thru hull 1 1/2" XL

Product Description

Elevate your marine plumbing system with our Straight Thru Hull Fitting, engineered to deliver superior durability and style without the weight and expense of full stainless steel. Crafted from fiberglass reinforced resin, this fitting offers excellent resistance to corrosion, flex, and harsh saltwater environments, making it the preferred choice for many saltwater boat builders and marine enthusiasts.

The polished 304 stainless steel cap, ultrasonically welded to the flange, adds an upscale, corrosion-resistant finish that protects your fitting from sun and salt damage—common issues with standard plastic thru hulls. This combination of materials ensures long-lasting performance and an attractive look on any vessel.

Designed with hose barbs to fit a 1-1/2" ID marine sanitation hose, our thru hull fitting accommodates various marine sanitation and plumbing setups. The extra-long threaded shank easily fits transoms up to 3-1/2" thick, offering flexible installation options for different boat builds.

For added convenience, the fitting includes a mounting nut for secure and hassle-free installation. Whether you're upgrading existing fittings or outfitting a new vessel, trust this thru hull fitting to deliver reliable, leak-free performance.
