For modern kitchen taps, that has an aerator cartridge; provides a secure method of temporarily attaching a Hozelock connector to a kitchen tap. Simply remove the existing aerator cartridge from the end of the tap, and then screw in the new Hozelock cartridge. Includes a tap connector; just screw this onto the ¾″ bsp thread when you want to connect the hose to the tap. For the rest of the time the plastic tap connector can live in a kitchen drawer.
