The V-ring is an all-rubber seal that mounts directly on the shaft and seals axially against a counter face, housing, seal case or similar surface. The long flexible lip is designed to act like a mechanical face seal. It can retain lubricants and exclude contaminants. V-rings can be used as a primary seal or as a secondary back-up seal.

If performs well in dry applications and is capable of handing a greater amount of eccentricity and misalignment than most radial lip type seals.
