Instructions for Use:

This product consists of two working bellows that withstand external pressure, one balancing bellows that also withstands external pressure, as well as structural components such as end tubes, connecting pipes, outer tubes, and end ring assemblies.

A compensator primarily used to absorb axial displacement and balance the thrust generated by bellows pressure.
