Fill adapter for Egressor package
Our standard Egressor packages are built with a tank valve / 1st stage combo. This allows one to refill their small pony bottle several times off of a larger scuba cylinder while the pressure remains greater in the larger bottle.
One end of this fill adapter screws into the valve/ 1st stage combo, the other end tightens down onto the larger tanks standard K valve. Open both valves and the air flows from the large bottle to the Egressor pony bottle.
