John Guest Fittings

Our PI and PM fittings are manufactured in grey (for inch sizes) and black (for metric sizes) acetal copolymer, making them especially suitable for applications involving foodstuffs and potable liquids. They are, however, equally suitable for air and inert gases and can be used on N2/CO2 (installed in accordance with The British Beer and Pub Association Code of Practice) mixed gas dispense lines and in pneumatics applications and vacuum.

  • Push-fit technology
  • Quick disconnection without the need for tools
  • Food Quality and suitable for potable liquids
  • Suitable for soft metal or plastic tubes
  • Suitable for air or inert gases
  • Superior flow characteristics
  • Straight Adaptor – Nptf Thread
