Why choose a rubber expansion joint?

Rubber expansion joints and connectors are the ideal choice for many piping situations, and they have several uses.

Rubber expansion joints are most often used as a flexible connector between a vibrating piece of mechanical equipment and the pipeline. These rubber connectors are generally the best solution for isolating noise and vibration and to keep these unwanted dynamics from being transmitted down the pipeline to occupied areas. Single and double spheres are quite common for this application in conveying water in HVAC systems.

They can also be used to absorb pipe movements. Spherical connectors are available in either single sphere and double sphere to absorb greater pipe motions. Spool type expansion joints can be built with multiple arches to take up greater movements.

Rubber connectors will also provide for a reasonable amount of pipe offset caused by equipment settling.

There are many choices of styles and configurations of rubber expansion joints.  Consider these configuration choices
