Plastic push-fit valve to connect MDPE. The uniquely designed fitting incorporates stainless teeth to provide a tight and secure grip on the pipe. By turning the handle, less than 2 turns, the flow of water can be stopped. The connection is demountable if required, ensuring the system is easy to work when in the ground and needing to maintain and alter existing set-up. The all plastic construction reduces the possiblity of the valve seizing over time. Installation time is greatly reduced when compared against traditional fixing methods. Features
