A cylinder manifold is a group of gas cylinders, commonly used to supply gases via a pipeline. Via a valve manifold, the cylinders are often grouped into a primary and a secondary bundle. Initially, the gas from the primary bundle is used first, where the gas is consumed equally from all cylinders, as they are connected in parallel through a common outlet.

Once the levels in the cylinders are sufficiently low, a pressure transmitter switches to the secondary valve manifold, so that the primary cylinder bundle can be exchanged. Valve manifolds are used to supply gas from one central source to different usage points. In hospitals, for instance, manifolds are used to supply nitrous oxide, Entonox or oxygen.
