To Connect

• Finger tighten the black end nuts fully on to the valve body.
• Insert the tube into the fitting.
• Pull to check the connection is secure. It is good practice to test the system prior to leaving the site or before use.

To Disconnect

• Ensure the system is depressurised.
• Push the collet square against the face of the fitting by using fingers or with the help of John Guest’s Collet release tool.
• With the collet held in position the pipe can be removed.
• The fitting can be used without the need for replacement parts.

What Not To Do

• Do not use damaged or scored pipe.
• Don’t use hacksaws to cut the pipe or leave burrs on the end of the pipe.
• Don’t forget to push the pipe fully into the fitting, past both the collet (gripper) and the ‘O’.
• Do not insert fingers into into the fitting as the stainless steel teeth may cause injury.
• Remember to pressure test the completed installation according to the recommendation in the John Guest Technical Checklist.
