Note 1: Can be used for general industrial water. The surge pressure must not exceed the maximum operating pressure. If the surge pressure exceeds the maximum operating pressure, it will damage the fittings and tubes.
Note 2: The minimum bending radius is the representative value measured as shown in the figure on the left. The tubing may be bent if used under the recommended minimum bending radius. Please allow additional margin for flexibility.
- *Abnormal temperature rises caused by adiabatic compression can result in the tube bursting.
