Raritan Diverter Y Valve w/Fittings

The Raritan Diverter Y Valve with Fittings is an essential marine plumbing component designed for boats and vessels that require flexible water system management. Whether you're running a saltwater head system, freshwater distribution, or bilge pumping, this diverter valve allows you to redirect flow between multiple destinations with minimal deck space footprint. Built by Raritan, a trusted name in marine sanitation and systems, this Y valve solves the common boating challenge of managing multiple outlet demands from a single source without permanent, rigid installations.

This diverter valve's design accommodates input from any port, giving installers maximum flexibility during retrofit or new build scenarios. All port connections feature National Pipe Thread (NPT) specifications, meaning you can source compatible fittings from any local marine or hardware supplier—no proprietary parts required. The valve body is engineered to handle typical marine water pressures and flows while maintaining a low-profile footprint of 7 x 5 x 9 inches, making it ideal for tight engine compartments and cabin spaces. The modest 1.7-pound weight ensures no added strain on through-hull installations or manifold mounting brackets.

Experienced captains and marine technicians favor this valve for applications requiring silent, reliable operation—no motor-driven solenoids, no electronic complexity. Install it inline with your raw-water cooling loop, freshwater distribution, or waste discharge system. The NPT female connections accept both brass and stainless fittings, giving you corrosion-resistant options for saltwater environments. Proper sizing of inlet and outlet hose diameters ensures full flow capacity without turbulence or noise, critical for long-range cruising where engine and system sounds matter.
