Stainless capped resin thru hull scupper 1 1/2" short

Product Description

Enhance your boat’s drainage efficiency with our premium Straight Thru Hull Scupper, engineered to deliver unmatched durability and style. Crafted from robust fiberglass reinforced resin, this scupper is built to withstand harsh saltwater environments, offering long-lasting resistance to corrosion and UV damage.

The polished 304 stainless steel cap, ultrasonically welded to the flange, adds a sleek, upscale look while protecting the fitting from sun and saltwater exposure — a common issue with plastic thru hull fittings. Trusted by saltwater boat builders for superior performance, this scupper provides both aesthetic appeal and marine-grade reliability.

Designed with hose barbs to fit a 1-1/2" ID marine hose, this thru hull scupper is compatible with a variety of boat plumbing systems. Its recessed flapper, measuring 1-5/8" in diameter, ensures efficient water drainage while preventing backflow, keeping your boat dry and safe.

Installation is simple and secure thanks to the included mounting nut, saving you time and effort during setup. For easy maintenance, the flapper can be replaced separately using our convenient Scupper Flapper Kit 56677.
