ABSTRACT:
A seal for a space between two surfaces which are movable relative to each other such as a shaft engaging through an opening in a housing or the like comprising a seal body made of an elastic material adapted to be secured to one of the surfaces such as the housing. A groove is formed in the seal body which confronts the other surface periphery of the shaft and is formed by a pair of spaced wall portions which converge inwardly toward the other surface so that the base of the groove is wider than the groove at the outer terminal edges of the wall portions. A flexible strip is seated in the groove and has a face confronting the other surface coated with a fiber flock projecting beyond the terminal edges of the wall portions. The strip is of a transverse dimension greater than the spacing between the terminal ends of the wall portions so that the strip and fiber flock are self-supporting in the groove and may be easily assembled therein and removed for replacement when desired. The seal also includes a pair of outwardly directed sealing flanges on either side of the groove formed integrally with the seal body.
