Product Description
The coupler is a push-fit plastic fitting for the connection of plastic, copper, and CPVC pipe. It was designed, manufactured and assembled by John Guest Speedfit. It can be installed by simply pushing the fitting fully onto the pipe and twist the plastic nut clockwise to lock in place. Should the need arise to demount the connection unlock the nut and push the collet towards the body of the fitting and pull the pipe to release. The coupler fitting ensures an easier working environment in confined places, is approved for behind the wall installations and removes the need for hot works on site. Installation can be reduced by around 40% when compared to traditional fixing methods.
