John Guest offers fittings for every install from Elbows, Union Connectors, Union Tees, Dividers, Angle Stop Adapters, End Stops, Plugs, Reducers, Stem Adapters, Faucet Connectors and many other connections. Each fitting works by gripping the tube or pipe with small metal teeth built inside the collet or neck to hold the tubing in place; and an o-ring is on the interior of the fitting to make a permanent leak-proof connection and prevent any leaking.
John Guest quick connect fittings must be used with a high pressure, hard plastic tubing which can be found on our site or at your local hardware store like a Home Depot or Lowes. Tubing is typically made of polypropylene or polyethylene. These can also be used with metal tubing like copper but keep in mind that the connection part of the material should be smoothly sanded to ensure a secure seal.
To remove, use both forefingers to press and hold the neck (collet) around the tubing down against the fitting while pulling the tubing out simultaneously. To insert tubing, be sure to cut the tubing square with a sharp knife then insert it until you feel the fitting lock onto the tube. Pull the tube to ensure a secure seal.
