ABSTRACT:
A sealing and stripper ring for a rod-like component has an annular support part on which a sealing lip and axially spaced from it a first stripper lip are provided. A second annular stripper lip is placed coaxially in front of the first stripper lip on the side opposite to the sealing lip. At least as regards its stripper part (which in the operational position contacts the circumferential surface of the rod-like component) the second lip is made harder or stiffer than the corresponding engagement part of the first stripper lip.
