ABSTRACT:
The present invention provides an apparatus and method of utilization thereof of a quick disconnect coupling for attaching an end of arm tool (EOAT) to a robot or like wherein there is fluid communication between the robot end of the coupling and the EOAT of the coupling. The coupling of the present invention also is designed so that fluid communication can only occur after the coupling halves are joined and sealed together. Fluid communication is cut off before the coupling halves can separate from each other thereby minimizing leakage during the coupling operation.
