Flowtech Performance Valves

Flowtech™ free flow sea valves incorporate the valve body, thru-hull and the choice of all three sizes of hose pipe connections all in one set.

These high performance valves are available for 3/4" (19.05mm) , 1" (25.40mm) & 1-1/2" (38.10mm) hose sizes. The Flowtech™ valve pipe can be faired smooth to the boat's outer skin so that when the valve is closed, the internal plunger and valve creates a flush, fair & fast outer surface. Made of Marelon®.
