This item allows you to connect a 20mm MDPE water supply pipe to a garden hose through a wall plate and a PVC easy-turn dial tap. The kit includes an MDPE compression wall/back plate that can be easily mounted on a wall, fence, or post using the three provided screw holes. Once the backplate is secured, you can attach the tap. A roll of PTFE plumbing tape is included; apply a small amount to the tap threads to ensure a leak-free, upright position. The tap is made from tough, UV-resistant plastic and comes with a universal garden hose click-on connector.
