Installation on One-touch Fittings Lengths of tubes to be inserted into One-touch fittings are indicated on the outer layer of TRBU tubes. Cut the tube according to this indication, (Step 1) and then strip off the outer layer (Step 2) for installing into fittings. 8 x 5 8 x 5 8 x 5 SMC FR TUBE TRBU0805 8 x 5 Pitch indication: All installation lengths with same pitch Cut internal and external layers Strip off the external layer only Step 1 Step 2 SMC FR TUBE TRBU0805 8 x 5 SMC FR TUBE 1. Applicable for general industrial water. Please consult with SMC if using for the other kind of fluid. Also, the surge voltage pressure must be under the maximum operating pressure. 2. Refer to the burst pressure characteristics curve for other temperatures. Furthermore, abnormal temperature rises caused by adiabatic compression may result in the burst of the tube. 3. The value of the minimum bending radius is measured at the temperature of 20°C as shown in the figure on the right. Precautions Bend the tube into U-form at a temperature of 20°C. Fix one end and close loop gradually. Measure 2R when the tube breaks or is crushed. Be sure to read before handling.
