How To Install On One-Touch Fittings

Procedure
Caution
The length and pitch for mounting on one-touch fittings are indicated on the outer layer of the TRB tube. Cut the tube in accordance with the indications (step 1), then peel off only the outer layer (step 2) and mount on the one-touch fitting.
Caution
- 1. Applicable for general industrial water. Please consult with SMC if using other kinds of fluid. Also, the surge pressure must not exceed the maximum operating pressure. If the surge pressure exceeds the maximum operating pressure, it will result in damage to fittings and tubes.
- 2. Abnormal temperature rise caused by adiabatic compression may result in the tube bursting.
