Description

The Attwood Marine 3877-3 is a plastic 90-degree thru-hull connector designed for tight installations, such as livewell overflow drains. Its design eliminates hose kinking. The connector is made of white polypropylene and is intended for installation above the water line only.

Key specifications include a 3/4" I.D. hose size, a 1" maximum hull thickness, and a 1-1/2" flange diameter. It requires a 1" installation hole size and features a 1/2" drain plug.
