The John Guest Speed fit plastic push-fit connector is used for connecting plastic and copper pipes. Simply push the fitting fully onto the pipe and twist the plastic nut clockwise to lock it in place. To demount the connection unlock the nut and push the collet towards the body of the fitting and pull the pipe to release. It ensures an easier working environment in confined places and removes the need for hot work on site. It has been designed, manufactured, and assembled in the UK by John Guest Speed fit.
