The easy to use push fit system for Compressed Air
The John Guest range of push-in fittings and pipe provide the
ideal connection from compressorreceiver to air line service
components through to complete ring main and take off points.
A compressed air system can be installed quickly and easily,
compared with other installation methods, time savings of
at least 50% are easily achievable. No need to prepare
threaded pipe or solvent, all the connections can be made
with a simple push-in action. The system is then immediately
ready for use.
Complex systems can be assembled much more rapidly than with traditional methods and because
fittings are easy to disconnect, systems can be altered or extended with much reduced production down time. The fittings are produced in either a tough engineering plastics material or in brass in、 sizes 12mm to 28mm. They are intended for use with John Guest nylon pipe but can also be used with copper or aluminium pipe.
