ABSTRACT:
A seal assembly for a shaft comprises one or more annular sealing elements having an initial internal diameter larger than the diameter of the shaft. The elements are deformed by a pair of annular backup rings disposed on opposite sides thereof. The backup rings have opposed axially extending undulations therein for effecting axial deformation and radial contraction of the sealing elements upon advancement of the backup rings toward one another.
