ABSTRACT:
An apparatus and method is provided for automatically venting a fluid from at least a portion of a pressurized system. An interconnection between two devices in the system contains an automatic bleed valve configured to automatically seal a vent hole when the two devices are coupled together and to automatically unseal the vent hole before the two devices are separated. In an embodiment, an adapter includes a ring that both screws a connector onto a device and seals a vent hole. A pin is pushed into the vent hole as the connector is screwed to the device. To remove the adapter from the device, the ring is turned to both unseal the vent hole and to unscrew the connector from the device. Turning the ring releases the pin before the connector is unscrewed.
