This JG Speedfit push-fit fitting is designed for connecting plastic and copper pipe, allowing for the isolation of appliances like washing machines or dishwashers for maintenance or installation. The installation process is simple: push the valve fully onto the pipe and thread the appliance hose onto the valve. To demount, push the collet towards the fitting body and pull the pipe to release. This cold connection system requires no heat or flames, making installation approximately 40% faster than traditional methods. It is suitable for domestic hot and cold water systems and is designed for water isolation and emergency shut-off control. The fitting is removable and reusable without damaging the pipe or fitting.
