ABSTRACT:
A sealing ring for sealing a space between two concentric sealing surfaces engageable one inside the other comprising first and second sealing portions each having a sliding surface. The sealing portions engage each other at the sliding surfaces and upon insertion one of the sealing surfaces in the other sealing surface each and to side against each other along the sliding surfaces which are preferably provided with lubricant. In the sealing ring illustrated, one of the sealing portions has a substantially conical sliding surface and the other sealing portion is connected with the first sealing portion and from that point of connection extends along the conical sliding surface so that the second sealing portion covers substantially the whole conical sliding surface in the starting position for inserting one of the sealing surfaces into the other.
