Abstract
A pressure seal for a rotating shaft (3) is disclosed in which a rubber sealing ring (9) is arranged in a trapezoidal slot (4), the sealing ring being made so thin at the slot opening as to prevent the rubber from creeping beyond the edges of the slot opening during prolonged periods when pressure is applied to engage the sealing ring with the shaft.
