JG Speedfit MDPE Equal Elbow 20mm in Blue. This is a push-fit plastic fitting designed for connecting plastic and copper pipes. To install, simply push the fitting fully onto the pipe and twist the plastic nut clockwise to secure it. To demount, unlock the nut and push the collet towards the fitting's body while pulling the pipe. This fitting is ideal for confined spaces as it eliminates the need for hot works on site, potentially reducing installation time by around 40% compared to traditional methods. Note: A manufacturer's pipe insert is required for all plastic pipes.
