Abstract: An adapter device includes a bracket having a wall and a fence extended from a base panel, the fence includes an opening formed by two arms for receiving a pipe, a tube is threaded to the wall and has one end movable toward and away from the fence. One or more plugs are selectively engaged between the tube and the pipe for making a tight seal between the tube and the pipe. One or more of the plugs may include a blind structure to block the tube and the pipe, or may include an orifice for communicating the tube and the pipe with each other.

Abstract: A desiccator container is installed in a refrigerant pipe of an automobile air conditioner for absorbing water contained in refrigerant. The container comprises an inlet connector, an outlet connector, a test connector, a pair of first bolts, a pair of second bolts smaller than the first bolts, four first threaded holes, and three second threaded holes smaller than the first threaded holes. This can increase the adaptability of the desiccator container, thereby reducing the manufacturing and maintenance costs.
