Railway vehicles

In rail traffic, flexible HYDRA® bellows elements generate additional safety and comfort. For example when they are used as a functional component in the tilting technology of the Pendolino tilting train or as a decoupling element in exhaust and fluid lines feeding the motor. The robust and absolute pressure-tight flexible HYDRA® metal tubes are preferably used in hydraulic systems.
