Abstract: A seal ring has a reinforcing ring with an inwardly-directed conical extension and a lip ring having elastic properties which embraces said extension in the manner of a U for a relatively-rotatable seal and bears on the shaft to be sealed as a static seal. The lip ring is a length of hose enlarged on one side to form an outwardly-directed flange. The hose portion of the lip ring is inserted into the extension of the reinforcing ring in the direction of its conical narrowing with the resulting elastic deformation at the flange tipping up the hose portion to form the U.
