Abstract
A sealing element for use with a radial lip oil seal includes a mounting section formed of a first polymer and a sealing section formed of a second polymer. The sealing element sections are bonded together during a common sintering operation so that each polymer is sintered only once. This reduces molecular degradation of the polymers typically caused by multiple sintering operations.
