Sea-Dog 520750-1 Thru-Hull Fitting 1-13/16 in White
Sea-Dog 520750-1 Thru-Hull Fitting 1-13/16 in White — Product description
The Sea-Dog 520750-1 is a white polypropylene thru-hull fitting for above-the-waterline drainage. The 1-13/16 inch barb grips standard drainage hose, and the corrosion-free body holds up to sun and salt spray season after season.
This Sea-Dog thru-hull fitting handles above-the-waterline drainage, the kind of job you'll find all over a boat. Think cockpit scuppers, livewell overflow, bilge vent lines, anywhere water needs a clean path out through the hull. It's molded from white polypropylene, so it won't corrode and it stands up to sun and spray season after season.
The barbed end measures 1-13/16 inches outside diameter and the body runs 3-1/2 inches long, which gives you plenty of hose grip. You run a hose over the barb, clamp it down, and you're done. Because it's rated for drainage above the water line, keep it for exactly that. It isn't a below-waterline fitting, so don't drop it below your load line.
It's sold as a single fitting. Whether you're replacing a cracked old thru-hull or rigging a new drain, this one's a simple, honest piece of hardware that just does its job.
