Abstract: A system including an coupler configured to be coupled to an adapter, the coupler including a body defining a fluid path through which vapor is configured to flow, and a valve positioned in the fluid path. The valve is biased to a closed position and configured to be moved to an open position when the coupler is coupled to an adapter. The coupler further includes an arm coupled to the body, wherein the arm includes a first arm portion located on a first side of the body and a second arm portion located on a second, opposite side of the body. The arm is configured to be moved to an energized position wherein the first and second arm portions are both biased radially inwardly. The arm is thereby configured such that when the coupler receives the adapter, having a groove, in the coupler at a sufficient depth the first and second arm portions each move radially inwardly into the groove to thereby couple the coupler and the adapter.
