Claim:
A portable gas delivery apparatus, comprising: a gas control device configured to couple to a compressed gas cylinder and comprising an integrated regulator, a fill valve and a dial configured to rotate about a central axis to thereby control gas flow from the compressed gas cylinder through the regulator; and a multi-piece body comprising: a first body portion and a second body portion forming substantially symmetrical halves of a housing configured to encase at least a portion of the gas control device, wherein the first and the second body portions engage one another at an interface to form the housing, the interface being disposed on a longitudinal plane; wherein the first and the second body portions form a first opening at the interface through which the dial is disposed, and the first and the second body portions form a second opening at the interface through which a pressure gauge is disposed; and a handle sized to accommodate a human hand, the entire structural length forming the handle is configured to a) be disposed on an axis oriented orthogonally to the longitudinal plane of the interface where the first and the second body portions engage one another and b) be offset from the central axis of the dial; wherein the handle is supported from the multi-piece body by at least one curved extension of the first body portion wherein the handle is further supported by a second curved extension from the second portion separated from the at least one curved extension of the first body portion by the handle and the dial.
