How To Use the Quick Connect Fittings

To make a connection, the tube is simply pushed in by hand; the 

unique patented John Guest collet locking system then holds the 

tube firmly in place without deforming it or restricting flow.

Cut the Tube Square

Cut the tube square and remove burrs 

and sharp edges. Ensure that the outside 

diameter is free from score marks. 

Push the tube into the 

fitting and up to the 

tube stop

Push Up to the Tube Stop

Pull to Check Secure

To disconnect, ensure that the 

system is depressurized, push the

the collet held in this position the 

tube can be removed.

Pull on the tube 

to check that it is 

secure. Test the 

system before use
