The reducer push-fit plastic fitting for the connection of plastic and copper pipe. It has been designed, manufactured and assembled in the UK by John Guest Speedfit.
 
 
 
Simply push 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 reducer fitting ensures an easier working environment in confined places and removes the need for hot works on site. Installation can be reduced by around 40% against traditional fixing methods.
