ABSTRACT:
A gas mask liquid delivery system including a gas mask having a liquid inlet port. A liquid control adapter having a body with a first end with an outlet opening formed therein, a second end with an inlet opening formed therein, and an interior chamber formed within the body. An inlet chamber extends from the inlet opening to the interior chamber and an outlet chamber extends from the outlet opening to the interior chamber. The inlet and outlet openings, inlet, interior, and outlet chambers, define a flow path when placed in open communication with each other to permit liquid to flow through the flow path. A stopper controls the flow of the liquid through the flow path. The outlet opening connects the adapter to the liquid inlet port. A flow tube connects a liquid source to a connector, wherein the inlet opening of the adapter is connected to the connector.
