Description for John Guest PEI203628

Note: Pipe Inserts are required for heating applications (and recommended for plumbing applications) when making a connection to PEX (an insert is required for each end of the fitting being connected to PEX). These inserts are sold separately.

Push-fit plastic fitting for use with copper pipe, CPVC, and PEX pipe. Designed, manufactured and assembled 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 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.


  • Push-fit connections
  • Suitable for use with PEX, CPVC and Copper pipe.
  • Hot and Cold water and Hydronic Heating applications
  • Lead Free and Non Toxic
  • Truly demountable without damage to pipe or fitting
  • No risk of fire or flames
  • Corrosion free and no scale build-up
NOTE: Speedfit fittings cannot be used on stainless steel pipe.
DO NOT USE FOR gas, fuel oil or compressed air applications.
