Step 1 - Cut Tube Square

Cut the 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 thin walled plastic tubing we recommend the use of a tube insert.

Step 2 - Insert Tube

Fitting grips before it seals. Ensure tube is pushed into the tube stop.

Step 3 - 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.

Step 4 - Pull To Check if Secure

Pull on the tube to check that it is secure. It is a good practice to test the system prior to leaving site and/or before use.

To disconnect, ensure the system is depressurized before removing the tube. 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.
