ABSTRACT:
A sealing element is provided which is formed of a fluorocarbon resin sheet and radially slit into two annular overlapping flaps to receive a garter spring or the like therebetween at a location adjacent to that peripheral portion of the element which is left solid and formed with a sealing edge. Despite the limited elasticity of the seal material per se, the sealing element, finally molded into shape, has an exceedingly high ability to follow the mating surface of a rotating shaft or other member of a mechanical assembly to be sealed. The followability of the sealing element is further improved on account of the slit formation of the element.
