Fix one end and close loop gradually. Measure 2R when the tube breaks or is crushed. Maximum operating pressure Brust pressure 1. Please consult with SMC regarding other fluids. Because ester polyurethane is used, water cannot be used due to the occurrence of hydrolysis. 2. The value of the max. operating pressure is at a temperature of 20°C. 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 above. Fixed end Model O.D. (mm) I.D.
