Expansion Joints Potable Water

These expansion joints piping are made of one single bellows element with end connections.

Regardless of pipeline accessories, such as liners and covers, this model absorbs all of the movements in any one length of piping but it is mainly used to absorb axial movements.

It does not restrain pressure thrust so adequate anchors and guides must be provided and they can be used only in potable water piping systems that incorporate correctly designed anchors and pipe alignment guides.


  • Absorbs axial, lateral, and angular movements
  • Must be properly guided
  • Does not restrain the pressure thrust
  • Requires main and directional anchors
