The seal is in the form of a pair of compressible sealing rings positioned between the mutual surfaces of the two members on opposite sides of the annular recess. A pressure indicator is connected to a gas supply line supplying gas to the annular recess to provide an indication of the pressure of gas prevailing in the annular recess, and particularly of changes of such pressure.
