John Guest Speedfit Airline Ring Main
The John Guest range of push-in fittings provide the ideal connection from compressor receiver to air line service components through to complete ring main and take off points. Using the John Guest system a compressed air ring main can be installed quickly and easily, considerably reducing the need for specialist staff and providing much reduced production down time
No need to prepare threaded pipe or apply solvent, all the connections can be made with a simple push-in action. The system is then immediately ready for use. Because the John Guest system is so easy to disconnect, alterations and extensions can be achieved with a minimum of production shutdown.
