ABSTRACT:
A rotatable coupling for a plurality of conduits for different media, comprises a core member with a number of axial passageways connecting to conduits coupled to the core member at various levels. The conduits communicate with annular spaces defined between the core member and a plurality of stacked rotatable ring members. The core member is made up of a stack of bodies connected to each other by tension bolts or the like, these stacked bodies having radially projecting flanges between which the rotatable rings are axially confined. The rotatable rings have ample play both in axial and in radial directions.
