Claim:
1. A hinge coupling assembly, comprising: a first coupling incorporated within a first hinge section coupled to a door, the first coupling including a first end and an opposite second end connecting a first coupling passage formed within the first coupling; and a second coupling incorporated within a second hinge section separate from the first hinge section and coupled to a door frame, the second coupling including a first end and an opposite second end connecting a second coupling passage formed within the second coupling; wherein connection and disconnection of the first coupling to the second coupling to create a single sealed continuous passage formed by the first coupling passage and the second coupling passage results upon installation and removal of the door to the door frame; and wherein, when connected, the first coupling is moved rotationally and axially relative to the second coupling as the first coupling is rotated relative to the second coupling while still maintaining a fluid connection between the first coupling and the second coupling upon rotational and axial displacement of the first coupling with respect to the second coupling, wherein the first coupling includes a first position at which the first coupling is fully seated within the second coupling and maintains the fluid connection, and wherein the first coupling includes a second position at which the first coupling is displaced rotationally and axially from the first position so that the first coupling is moved partially out of the second coupling and maintains the fluid connection; and wherein the sealed continuous passage is maintained upon rotational and axial displacement of the first coupling with respect to the second coupling upon opening and closing of the door.
