ABSTRACT:
Three pressure elements are employed in reducing the transverse area circumscribed by the outer periphery of a resilient ring type seal to permit its placement in a groove formed in a bore which is smaller in circumference than the outer periphery of the seal. One pressure element is applied to the outer periphery of the seal, and two to its inner periphery at points which are spaced equally on either side of a line which extends from the center of the seal through the outer pressure element. The two inner pressure elements are then rotated outwardly in opposite directions around the outer pressure element to fold a portion of the seal inwardly on itself around the outer pressure element, thereby reducing the transverse area circumscribed by the outer periphery of the seal. While so reduced, the seal is placed within the bore opposite the groove, and the outer pressure element then drawn axially out of engagement with the outer periphery of the seal to permit its expansion into the groove.
