A unitized radial fluid seal includes a shell having a first elastomeric seal body affixed thereto and defining a primary seal lip. A sleeve includes a substantially cylindrical, axially-extending sealing flange and a protective flange extending substantially radially from the axially-extending sealing flange. A spring radially urges the primary seal lip into sealing contact with a sealing surface of the axially-extending sealing flange. A second elastomeric seal body is affixed to the sleeve and includes a resiliently-elastic angled lip extending from a terminal end of the axially-extending sealing flange opposite of the radially-extending protective flange. The sealing surface and an axially-outward facing surface of the angled lip define an angle (&#x3b1;) that is between about 130-170&#xb0;. The primary seal lip is axially retained between the angled lip and the radially-extending protective flange.
