ABSTRACT:
A seal for a reciprocally moving body that has at least one essentially flat boundary surface extending parallel to its longitudinal axis includes a sealing member that has a first sealing lip formed of polymer material. The first sealing lip extends substantially parallel to the longitudinal axis and abuts the boundary surface. The first sealing lip also has a larger cross-section near a middle portion of the flat boundary surface than in an area of its lateral edges.
