VALVE MPT X BARB

These Barbed Valves are designed for simple and secure control of water flow in low-pressure plumbing systems such as ponds, irrigation lines, fountains, and hydroponic setups. Each valve features a 1/2-inch male pipe thread (MPT) on the inlet and a barbed outlet—either 1/2" or 3/4"—to connect directly to flexible tubing.

Made from UV-stabilized plastic, these valves are tough, reusable, and perfect for outdoor installations. Just thread into your pump, manifold, or riser and slide flexible tubing over the barb to control water direction or shut off flow.

• Barbed Outlet: Fits either 1/2" or 3/4" tubing (depending on model)
