Multiple feature
Composite material complement the feature of each other. Fluoropolymer liner for chemical and heat resistance, and rubber cover for vibration absorption.


Pressure Resistance
Besides the fluoropolymer liner, the tire cord withstanding internal pressure. Maximum design pressure is up to 1.6MPa, (16.3kgf/cm2 ), and a negative-pressure of minus 0.086MPa, (minus 650mmHg).


The exterior rubber absorbs unexpected impacts and protection cover is not required for exposed applications.


Hot-water supply line
Fluoropolymer liner with a maximum operating temperature of up to 100°C. U-FLEX is suitable for hot-water supply application without any contamination.





Vibration absorption for equipment, such as pumps.




Operating Conditions and Performance







Pump installation, such as hot-water supply lines, chemical lines, and pure water lines.








Dimensions and Allowable Movements


● Mass is the data when material is SS400, and flange is JIS10K flange.

● Use a joint within the range of allowable displacement.

● Fixing allowable dimension is included in allowable displacement (allowable displacement = fixing time

 displacement + operation displacement).

● Each displacement in chart are data of single displacement, so for multiple displacements, correction is necessary.

 For correction method, refer to “Attention for handling or “TOZEN HP”.

● Referring to “fixing bolt dimension table” , and use fixing bolt. Nut is not necessary. (When companion flange is

 JIS 10K, material is SS400, and when plain washer and gasket are not used.)
