Abstract: A gas valve apparatus is configured to receive a gas specific adapter. The apparatus includes a gas valve body having a first end configured to be coupled to a gas connection and a second end. A keyed body is configured to receive the second end of the gas valve body. The keyed body has a first keying mechanism. The apparatus also includes a cap coupled to the keyed body. The cap includes a keyed front face having a gas outlet configured to receive the gas specific adapter. The cap also includes a second keying mechanism configured to mate with the first keying mechanism on the keyed body to permit the cap to be coupled to the keyed body.

Abstract: A swiveling fluid connector includes a flexible fluid conduit connected to a check valve mounted for rotation. The flexible fluid conduit is connected between the check valve and a stationary fluid conduit. The check valve is mounted for rotating considerably with respect to the stationary fluid conduit. The flexible fluid conduit flexes to allow for rotation of the check valve relative to the stationary fluid conduit, and maintains leak-tight communication between the check valve and the stationary fluid conduit. The check valve extends through an aperture in a plate mounted in a gas services unit. Flanges on opposite ends of the check valve cooperate with the opposite surfaces of the plate to retain the check valve in the aperture, yet allow rotation of the check valve. The rotation of the check valve is limited to an acceptable range by the cooperation between protrusions and stops. The protrusions are connected to and travel with the check valve.
