ABSTRACT A torsional vibration damper of the type having an inertia ring member and a hub member coupled together by an elastomer member. The hub member may be in the form of a disc and is adapted to be coupled to a rotating shaft subject to torsional vibrations, the elastomer and inertia ring member acting in a known manner to damp torsional vibrations. According to this invention a seal, termed a dust and oil slinger, is mounted on the hub. The seal overlies the elastomer and protects it from dust ox other particles and from corrosive fumes and liquids. The seal may additional serve as a sacrificial member which will, in certain corrosive ambients, degrade prior to degradation of the elastomer connecting the hub and inertia ring. The seal is either integral with the working elastomer member, or is formed by adhering to the working elasto- mer member a sealing material of a different composition.
