An annular bourdon tube gauge assembly comprises a bourdon tube member, a first flange element, a second flange element and a pressure level indicator, and is adapted to be mounted externally circumferentially of a portion of a body member that is adapted to confining a pressurized fluid, such as a pressure regulator. The bourdon tube is axially disposed between the first and second flange elements, and has a spiral shape, a radially inner end and a radially outer end. The radially inner end is fixed with respect to the portion of the body member. The radially outer end is free to move circumferentially responsive to changes in the fluid pressure entering a pressure receiving port at the radially inner end. The pressure level indicator is mounted to and moveable with the radially outer end, and is viewable from a position located laterally outward of the first and second flange elements.
