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.

• Installation time reduced by at least 50%
