Rubber Expansion Joints

Rubber expansion joints are particularly suited to compensate mechanical vibrations, compensate axial and lateral movements, compensate installation misalignments and retain sound.
Rubber expansion joints with tie rods that are supported by rubber mountings are especially suited to retain sound and to compensate movements in plants where the installation of pipe anchors to withstand pressure thrust is impossible.
