T-H Marine Y-750 Barbed Wye Y-Fitting, 3-Way, 3/4 Inch Hose

The T-H Marine Y-750 is a barbed wye (Y) fitting molded specifically to fit marine hose dimensions, designed to create branch lines in a boat's hose plumbing. Unlike a standard tee fitting, a wye fitting joins three hose legs with the side inlet entering at a 45 degree angle rather than a straight 90 degree angle, which reduces friction and turbulence that could otherwise hamper water flow. This angled design makes the Y-750 useful anywhere a boat owner needs to combine or split hose runs, such as directing drainage from multiple sources into a single line, and it can improve drainage efficiency while also simplifying installation where space is limited.

All three legs of the Y-750 share the same barb dimension, sized for 3/4 inch inside diameter hose, so each connection seals consistently without needing different size clamps on different legs. The fitting is molded from black nylon, giving it resistance to the marine environment while keeping the part lightweight and compact. By combining multiple smaller hose runs into fewer exit points, a wye fitting like the Y-750 can also reduce the total number of holes that need to be cut into a hull for exit fittings, saving both material cost and installation time.
