Regulate or shut off water circulation in your above-ground pool filtration system with this heavy-duty 2-way shutoff valve. Built with a 1.5-inch male pipe threaded (MPT) port on one side and a multi-diameter stepped hose adapter on the other, it connects directly into skimmer housings, pump inlets, or filter tanks while securing flexible 1.25-inch or 1.5-inch pool hoses.
