Examples of applicable lines


Rubber flexible expansion joints.

  • ●When ground subsidence is anticipated
    Install on soft ground, roads, river crossings etc. it absorbs mainly perpendicular and bending displacement.
  • ●When temperature variations are anticipated
    Installed on piping where temperature differences, thermal expansion, etc. are anticipated mainly to absorb axial and bending displacement.
  • ●When vibration and noise are generated
    Installed near pumps or turbines to absorb vibration and noise transmitted to pipelines.
  • ●When multiple causes are anticipated
    Products can also naturally be installed when causes among the above occur together.
  • ●Cases of incompatibility with other TOZEN products
    When on-site usage with products of specifications such as the PT Connector, TOZEN Flex, and TOUGHLEX is not possible.
