Flowtech free flow sea valves incorporate the valve body, thru-hull and the choice of all three sizes of hose pipe connectors all in one set. These high performance valves are available for 3/4" (19.05mm), 1" (25.14mm) & 11/2" (38.1mm) hose sizes.

The Flowtech valve can be faired smooth to the boats outer skin so that when the valve is closed, the internal plunger and valve pipe creates a flush, fair and fast outer surface. Made of Marelon®.
