Installation and Maintenance
Installation requires cutting the pipe square and using a push-fit action. The system is ready for immediate use, with fittings easily disconnected and reused. John Guest pipe cutters are recommended, and fittings and pipes should be clean and undamaged.
Unique Features
Fittings include a collet with stainless steel teeth and an 'O' ring for a leak-proof seal. The Water Trap Tee prevents moisture entry, and the Stem Elbow allows flexible pipe orientation.
Technical Specifications
The system operates from -20°C to +70°C and handles pressures up to 10 BAR at 23°C, compatible with UPVC, ABS, and copper pipes.

Side Loads and Installation Guidelines
Products should not be used under side loads. Tubes must align well with fittings, and damaged fittings should be replaced immediately.
Pneumatics Fittings
Super Speedfit Push-in fittings offer quick, secure connections for pneumatic applications, suitable for plastic and soft metal tubes, handling up to 10 bar and vacuum applications.
SuperThread Technology
Allows male adaptors to be used with various female thread forms without additional sealant, providing superior flow characteristics and a compact design.
Technical Specifications
Fittings operate within 5ºC to 70ºC and 0.5 Bar to 10 Bar. Air supply should be filtered to 50 microns.

No need to prepare threaded pipe or solvent, all the connections can be made with a simple push-fit 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, aluminum pipe or copper and can also be used on vacuum application. • Installation time...

EASY TO MAKE A CONNECTION ‘O’ Ring Pipe Stop Stainless Steel Teeth Collet The John Guest Push-fit Fitting has a collet (gripper) with stainless steel teeth which hold the pipe firmly in position and an ‘O’ ring to provide a permanent leak proof seal. THREE EASY STEPS Fittings and pipe should be kept clean and undamaged before use. Cut the pipe square. We recommend the use of the JG Pipe Cutter. DO NOT use a hacksaw. To avoid damage to the ‘O’ ring remove burrs and sharp edges. Push up to pipe stop. Pull to check secure. Test the system before use. To disconnect, ensure the system is depressurised....

28mm fittings also have a collet with stainless steel teeth and an ‘O’ ring. After inserting the pipe, a screw cap is turned approx 1/4 turn. This locks the collet in place and reduces lateral and sideways movement of the pipe. To disconnect, turn the screw cap 1/4 turn, push in the collet and remove the pipe. The fitting and pipe can be reused. Nylon, Copper & Aluminium Pipe Whilst we recommend the use of John Guest Rigid Nylon Pipe, John Guest Fittings can also be used with copper or aluminium pipe.
