JG 1/4 inch Union Tee - White

JG 1/4 inch Union Tee - White


Item #: RO5271

Temporarily Out of Stock

Color: White
John Guest Part# : CI0208W
Tube O.D.: 1/4"

How to make a connection
  • Cut tube square
    It is essential that the outside diameter be free of score marks and that burrs and sharp edges be removed before inserting into fitting. For soft or thin walled plastic tubing we recommend the use of a tube insert.
  • Insert tube
    Fitting grips before it seals. Ensure tube is pushed in to the tube stop.
  • Push up to tube stop
    Push the tube into the fitting, to the tube stop. The collet (gripper) has stainless steel teeth which hold the tube firmly in position while the "O" ring provides a permanent leak proof seal.
  • Pull to check secure
    Pull on the tube to check it is secure. It is good practice to test the system prior to leaving site and/or before use.
Push in Collet and remove tube

To disconnect, ensure the system is depressurized before removing fitting. Push in collet squarely against face of fitting. With the Collet held in this position, the tube can be removed. The fitting can then be re-used.

Perfect Fit

The John Guest parts work very well and I don't have to worry about leaks. I used this fitting to T my RODI effluent line. One line goes to the barrels and one goes to the wastewater. Add some ball valves and I can easily flush the membrane prior to filtering water.
