A prosthetic socket having an aperture at its distal end is fitted with a seal that is configured in such a way that a tension applied to the said prosthetic socket produces a self-generating force at the seal as a result of the atmospheric external pressure increasing the sealing action provided by the sealing lip. The seal may be affixed to the prosthetic socket and/or to a liner, the sealing edge always being radially nearer the aperture to be sealed than is the root of the sealing lip.
