Polytetrafluoroethylene (PTFE) bellows or polytetrafluoroethylene (PTFE) expansion joints and polytetrafluoroethylene (PTFE) compensators combine the high corrosion resistance and excellent bending ability of PTFE.

PTFE bellows are suitable for all chemical products and compensate for repeated thermal expansion in the pipeline. They are also widely used to protect equipment from vibration and pipeline loads.
