Abstract: Seal for a generally annular gap between a pair of relatively rotatable or reciprocatory annular machine members, one member having at least one continuous perimeter surface portion located in the gap or in contiguity to the gap, and the other member having a corresponding surface portion located in the gap or in contiguity to the gap, respectively, characterized by a first coating of an adhesive material applied to said one surface portion, and a second coating of a multitude of closely spaced short flexible fibers of a generally equal length supported in said adhesive material, and said fibers being generally oriented with respect to said one surface portion, each fiber being independently secured solely at one end by said adhesive to said one surface portion, and at least a plurality of the free fiber ends in anti-frictional contact with said corresponding surface portion of said other member.
