Speedfit push-fit fitting for the connection of plastic and copper pipe. The valve allows isolation of appliances such as a washing machine or dishwasher for maintenance or installation. Simply push the valve fully onto the pipe and thread the appliance hose onto the valve. Should the need arise to demount the connection pull 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. Designed, manufactured and assembled in the UK by John Guest Speedfit.
