Abstract
A wiper seal is disclosed which includes an elastomeric member having a metal support member adhesively bonded thereto. The elastomeric member has a first substantially flat surface that is perpendicular to a reference axis of the wiper seal, an outer peripheral surface that is substantially parallel with the reference axis, and an inner peripheral surface that forms an acute angle with the reference axis. The metal support member has a first leg portion that coincides with the outer peripheral surface and a second leg portion that coincides with the substantially flat perpendicular surface. The intersection of the first and second leg portions forms a generally sharp corner or at least a predetermined minimum radius size. When the wiper seal is installed in a recess of a housing, the substantially flat perpendicular surface is generally flush with the surface of the housing adjacent the recess to substantially eliminate recesses or pockets that could retain dirt and/or other contaminants.
