How To Install On One-Touch Fittings
Procedure
The length and pitch for mounting on one-touch fittings are indicated on the outer layer of the TRBU 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 contact 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.
- 3. The value of the minimum bending radius is measured at the temperature of 20°C as shown in the figure below.
Minimum bending radius
Bend the tube into a U shape at a temperature of 20°C. Fix one end and close the loop gradually. Measure 2R when the tube breaks or is crushed.
