Description for John Guest PSEI4620

Note: A TSI20 Insert is required for heating applications (and recommended for plumbing applications) when making a connection to PEX. This insert is sold separately.

NOTE: Speedfit fittings cannot be used on stainless steel pipe.
DO NOT USE FOR gas, fuel oil or compressed air applications.

Push-fit plastic fitting for use with copper pipe, CPVC, and PEX pipe. Designed, manufactured and assembled by John Guest Speedfit. A must for any tool bag. The unique feature of the Speedfit concept, the ability to disconnect the fitting at will, means that the end cap provides a leak proof seal and can be removed at any stage in order to allow work to restart or allow an extension to the system. This makes the fitting the perfect tool for when water needs to be turned back on, overnight for instance, or if a job suffers an interruption. End caps are also useful when pressure testing a system before appliances are connected. Simply push the fitting fully on to the pipe, there is no need for tools, sweating or threading. Should the need arise to demount the connection push the collet towards the body of the fitting and pull the pipe to release.


  • 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

  • Reusable many times over
