Stainless capped resin thru hull scupper 1 1/2"

Product Description

Enhance your boat’s drainage efficiency and durability with our premium Straight Thru Hull Scupper, engineered for superior performance in harsh marine environments. Trusted by saltwater boat builders and marine professionals alike, this scupper blends rugged construction with an upscale aesthetic, providing long-lasting reliability without the weight and cost of full stainless steel fittings.

Crafted from high-strength fiberglass reinforced resin, this scupper withstands saltwater corrosion, sun exposure, and rough conditions. The polished 304 stainless steel cap, ultrasonically welded to the flange, not only adds a sleek finish but also offers enhanced protection against UV and saltwater damage—common issues with traditional plastic thru hull fittings.

Designed with hose barbs to fit 1-1/2" ID marine hose, this thru hull scupper suits a variety of boat configurations and plumbing setups. Its compatibility with transoms up to 3-5/8" thick ensures flexible installation options. The included mounting nut simplifies installation, making it quick and secure.

The recessed flapper with a 1-5/8" diameter promotes effective drainage while preventing water backflow, keeping your vessel’s interior dry and safe. For easy replacement of the flapper, consider our convenient Scupper Flapper Kit 56677.
