    Understood. One is marked "Air" and the other "N2".

    A few microns or thousands of an inch can block interchangeability.
    Obvious when fitting parts; not in photographs. Fitting a UNC nut to a
    UNF screw is a more extreme example.

    One reason for labelling them and keeping them separate is that the oxygen one has to be kept free of inflammable lubricants etc.
