ERV Rubber expansion joints are flexible connectors for the construction of pipe systems.
They relieve system strain by reducing vibration, noise and compensate static or dynamic movements caused by thermal change, load stress, pumping surges or construction settlement.
The flexible nature of the high-grade rubber can compensate for assembling inaccuracies (misalignment during installation) and can be used as pipe insert pieces to facilitate inspections.

Typical applications include, water heating and cooling, boiler plants and engine rooms, water treatment, marine, petrochemical, potable water and food processes.
