GROCO STH-1250-W 1-1/4 Inch Bronze Combo Scoop Thru-Hull Strainer with Nut

The GROCO STH-1250-W is a 1-1/4 inch bronze combo scoop thru-hull strainer supplied complete with its mounting nut. It is installed through the hull below the waterline to draw in raw water for engine cooling, washdown, or other onboard water intake systems while keeping debris out of the plumbing line. The combo scoop design combines a strainer body with a scooped intake profile intended to help direct water flow into the fitting as the boat moves through the water.

Constructed of bronze with a bronze exterior finish, the STH-1250-W is built for continuous saltwater and freshwater exposure below the waterline, a standard material choice for thru-hull fittings due to its corrosion resistance in marine environments. It carries a marine grade rating and has a 1.25 inch thread size and diameter, matching standard 1-1/4 inch thru-hull plumbing. The fitting ships as a single unit with its nut included, allowing it to be mounted directly through a drilled hull opening and secured from the inside.
