Soft Polyurethane Tube

RoHS2 Compliant

Ultra soft polyurethane tube for air and water flow.
Extreme flexibility allows the installation in a narrow space where a tight bending radius is required.
Available in 6 colors and 5 sizes.

Bending radius

  • 6Color


Extremely flexible suitable where a small bending radius is needed

The excellent flexibility enables piping in a narrow space achives a small bend radius

Can also be used with water

Extruded from Ether type polyurethane.

Cutting marks are printed at approximately 500mm intervals

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

Fluid medium Air, Water (Conditional *1)
Max. operating pressure (65%RH at 20ºC) 0.6MPa *2
Max. vacuum -100kPa
Operating temperature range -15~60ºC (No freezing)
Remarks Use of Insert Ring is recommended. (Use Insert Ring where JIS standard pull-out strength is required. (JISB8381-1))


*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.
