The invention relates to a pipe-manifold piece for vacuum and gas lines, having a shaped body (1, 22) and having at least one connection pipe (2, 3, 4) branching off from this. In order to provide a pipe-manifold piece which can be used in a more universal manner than the prior-art manifold pieces and ensures the attachment of connection pipes of different diameters, the invention provides that at least one group of mutually coaxial centrings (13, 14, 15) of different diameter is arranged on the surface of the shaped body (1, 22) and that one connection pipe (2, 3, 4) of corresponding diameter can be fitted on one of the centrings in each case. <IMAGE>
