Abstract
A system and method for dispensing a pressurized fluid from a container into an automobile air conditioning system. A moveable plunger in an interior of a housing may engage an automobile air conditioning system valve and pressurized container valve to allow refrigerant and lubricant to flow from the pressurized container into the automobile air conditioning system. A quick-connect coupling may be used to couple the housing to the automobile air conditioning system after the housing has been snapped onto the pressurized container. In addition, the moveable plunger may be biased toward the automobile air conditioning system valve by a spring to ensure the automobile air conditioning system valve is opened when the housing is coupled to the automobile air conditioning system.
