Push-fit valve for the connection of plastic and copper pipe. The valve allows the user to stop the flow of water to a tap in case of emergency or repair via a 1/4 turn of a screw on the valve there is a 90 degree bent nut which can be tightened on to a side entry tap, toilet or male thread. Simply push the valve fully on to the pipe and connect the tap connection to the thread. Should the need arise to demount the connection push the collet towards the body of the fitting and pull the pipe to release. Installation can be reduced by around 40% against traditional fixing methods.
