Using ERRE.DI rubber expansion joints makes it possible to counterbalance the stresses and vibrations on the operating lines where the pipes are installed. Another useful feature of our rubber joints is that they absorb vibrations, significantly reducing noise, while also offering high corrosion resistance.
