Fluid medium Air, Water (Conditional *1), Others such as chemicals (Conditional *1)
Max. operating pressure (65%RH at 20º) 1.0MPa (*2)
Max. vacuum -100kPa
Operating temperature range -15~80ºC (No freezing)


*1) Adhere to the following conditions in case the fluid is water or any liquids

Surge pressure must be controlled lower than max. operating pressure when using water or any liquids as a fluid medium

Tap water in Japan, which is soft water (low mineral content) can be used. Carry out the evaluation under an actual operating condition for using other kind of water

Be sure to place Insert Ring (WR) into the tubing end when the tubing is inserted into Push-in Fitting with water or any liquids oil as a fluid medium

In case of using with water, the tubing can be discolored but it does not affect the performance of tubing

Can be used with numerous chemicals but please check the chemical compatibility before use

*2) The value of max. operating pressure is measured at 20ºC at 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
