A seal assembly is mounted on a shaft in sealing relationship to provide a sealed chamber in a housing from which the shaft extends. The seal assembly includes a unitary annular seal body attached to an annular retainer. The seal body includes three radial sealing lips in engagement with the shaft. A primary lip is adjacent the sealed chamber and provides the primary fluid seal. A secondary lip is rearward of the primary lip and keeps the primary lip aligned with the shaft. A rearward lip excludes environmental contaminants from entering the sealed chamber.
