Rubber expansion joints

Rubber expansion joints are used on units, machines, pumps, and in piping systems to absorb movement and dampen vibration and noise. They are both safe and economical to operate. Their ability to accommodate movement and dampen vibration, as well as to dissipate forces within the pipeline, helps protect adjacent components.

The type of restraint determines which movement can be accommodated and how the thrust reaction force is absorbed in a system. There are three different types of restraint:‍

  • Axial or universal

  • Lateral 

  • Angular
