The Hozelock Indoor Threaded Tap Connector is suitable for use with modern indoor taps with a 22mm female head and in-built aerator, when an outside tap is not available. To connect, simply remove the aerator head from your kitchen tap, then screw in the metal part of the connector, followed by the plastic 3/4 BSP tap connector. Your hose can now be attached with a quick click hose end connector. The tap connector forms a secure, watertight seal.
