ABSTRACT:
A quick connect/disconnect coupler having a slidable piston to connect and disconnect to a standard fitting or coupling attached to suitable tubing. The coupling is slidably received by the coupler and locked in place by the piston. In the locked position, the coupling depresses a valve pin in the piston which opens a passageway in the coupler. At the same time, a depressor in the coupler depresses a valve stem in the coupling, thereby allowing bi-directional gas flow to the device being serviced from the service apparatus, or vice versa. A method of charging or discharging refrigeration apparatus with said coupler is also disclosed.
