Fluid medium Air
Max. operating pressure (65%RH at 20ºC) 1.0MPa*
Max. vacuum -100kPa

*The value of max. operating pressure is measured at 20℃ and 65% RH. When the tubing is used in different conditions, consider a safety ratio of the pressure with an enough margin, referring to Burst Pressure Curve. When the tubing is frequently swung and bent, there is a possibility of generating heat between molecules and damaging the product.
