Bending radius

  • 10Color


Very flexible and kink resistant

Suitable for applications where maneuverability is required

Achieves a small bend radius and flexibility

Wide range of color options

10 colors are provided as standard for identification, tracing, color-coding purpose

The cut marks at 500mm interval are printed on the tube

It is useful to cut tubing. The mark is just as a guide and the accuracy is not guaranteed.

Tubings longer than the packaged length can be requested as build-to-order production

Fluid medium Air, Water (Conditional *1)
Max. operating pressure (65%RH at 20ºC) 1.0MPa (*2)
Max. vacuum -100kPa
Operating temperature range -15~60ºC (No freezing)


*1) Adhere to the following conditions in case the fluid media is water

Surge pressure must be controlled lower than max. operating pressure when using water 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 into the tubing edge when the tubing is inserted into Push-in Fitting with water as a fluid medium

*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. When the tubing is frequently swung and bent, there is a possibility of generating heat between molecules, and damaging the product
