Rubber Expansion Bellows are an assembly which are used primarily in piping applications to compensate for thermal expansion and contraction, reduce noise and vibration produced by the rotating element as well as relieve pipe stress during operation.

A Rubber expansion bellows consists of a specific number of convolutions, with the shape of the convolution designed to withstand the internal pressures of the pipe, but flexible enough to undergo axial, lateral, and angular movements.
