A gas extraction apparatus is used within a pressure vessel for extracting gas from the vessel while leaving liquid. A neck fitting is adapted for threaded engagement within a neck of a pressure bottle. An expansion chamber is threaded into the neck fitting. The expansion chamber extends distally and axially into the pressure bottle. The expansion chamber is threaded into the adapter fitting and a suction tube terminates with a circular flange engaged for rotation within the adapter fitting. A compression spring is fitted between the obverse side of the circular flange of the suction tube and a terminal distal surface of the expansion chamber. A seal is positioned between the reverse side of the circular flange and an internal annular surface of the adapter fitting. A further seal is positioned between the proximal end of the tube body and an annular seal retaining groove within the adapter fitting. An eccentric weight, and/or a floatation means, is fixed to the suction tube and is positioned for urging rotation of the suction tube to maintain a distal terminal end of the suction tube at an elevated position for suction of gas rather than the liquid within the pressure bottle.
