The GARDENA Hose Connector with Control Valve helps you quickly and easily change connection accessories without turning of the tap, especially suitable for high water pressure. The water valve is attached to the end of the hose and is compatible with 19 mm (3/4") hoses. Turn the valve to conveniently adjust the water flow or turn it off completely. This gives you the opportunity to change the connector on the spot and continue watering the garden without having to turn off the water at the tap. The connector is frost-proof, so you can use it all year round. The Hose Connector with Control Valve is made in Germany for high product quality and GARDENA offers a 5-year warranty.
