In a gland comprising two coaxial, relatively rotatable annular plates 1, 2 with opposite faces 7, 8 operatively separated by a narrow clearance in which a gas film is established, one or both of the faces defining annular grooves 10, 12, 14 alternating in radial sequence from one peripheral edge to the other with plain annuli 9, 11, 13, 15, at least two of the grooves, e.g. 12, 14, lying between one of the peripheral edges and another of the grooves, e.g. 10, to which gas is fed under pressure, are subject to pressures which are less than the feed gas pressure and diminish in magnitude towards the said one peripheral edge. The gland may be used to prevent leakage of a reactive or toxic process gas from a compressor casing 4 along its shaft 5 and also to prevent leakage of air into the compressor. The plate 2 is fast to the rotary shaft 5 and the plate 1, which is non-rotatable, is sealed to the casing 4 by a bellows 3, the plates being urged towards each other by springs 23 secured at 24. In the case when the gas in the compressor is at sub-atmospheric pressure, a barrier gas, such as nitrogen, at super-atmospheric pressure is fed to groove 10 via a manifold 20, holes 19 and orifices 18. Part of the nitrogen flows radially outwardly and prevents in-leakage of air; part flows radially inwardly, a fraction escaping to the atmosphere through vent holes 21 opening in the groove 12, another fraction being extracted through holes 22 opening in the groove 14 and connected through a pipe to a low-pressure pump, and the remaining fraction flowing over the inner peripheral edge of the plate 1 to prevent out-leakage of the compressor gas. The gland may also serve as a thrust bearing, the plate 2 being loaded against the plate 1 by the axial thrust on the shaft. The springs 23 may be dispensed with and the grooves 12, 14 may be formed in the face 8 of the plate 2, the holes 21, 22 thus extending right through the plate 1.
