Abstract
A hinge coupling assembly includes a first coupling incorporated within a first hinge section coupled to a door, 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. 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 second coupling passage is simultaneous upon installation and removal of the door to the door frame. The sealed continuous passage is maintained upon radial and axial displacement of the first coupling with respect to the second coupling upon opening and closing of the door.
