Perko 0456DP7 Inline Flushing Valve, 1-1/4 Inch Hose Connection

The Perko 0456DP7 is an inline check valve built for flushing and winterizing inboard engines with fresh water. It connects to a standard garden hose and uses water pressure to automatically pull fresh water into the boat's cooling system, so freshwater flushing becomes as simple as hooking up a hose. The valve is also commonly used to winterize an inboard engine at the end of the season, and it can be used with onboard generators as well.

This listing is for the valve only, sized for 1-1/4 inch hose connections. The valve body is built from polymer with stainless steel components for corrosion resistance in a marine environment, and it uses a 1-1/4 inch NPT threaded inlet and outlet connection. Perko also offers this same inline valve in 5/8 inch and 1 inch hose sizes, and a companion Valve & Kit version for buyers who need the mounting kit included, so be sure to match the hose size and configuration to your engine's flushing setup.
