A tubular bellows element for fluids is provided which has concentric corrugations. The corrugations include flanks separated by spaces which narrow towards inner ends of the corrugations. The inner corrugation ends have a conical shape, and act as scales to increase the degree to which the ends of the bellows element can be moved with respect to each other. The inner ends also serve to provide an essentially smooth inner surface for the bellows element, minimizing both flow disturbance and the creation of turbulence.
