In such cases, for a scupper, sink drain, and bilge pump overboard discharge, this POLY Through-HULL (WHITE) 5/8 Inch (3-520740-1) fitting connection for the hose is highly effective. These are carefully built for use with a hose for drainage above the waterline, allowing water to pass in and out of the vessel, and are ideal for saltwater use because of the sturdy, marine-grade injection-molded polypropylene construction that does not corrode, rust, or cause electrolysis. All materials are UV stabilized to provide longevity and trouble-free service results.
