The V-ring is an elastomer seal. It is expandable and can be easily pulled over flanges and housing parts. The V-ring has an undersize inner diameter and is held firmly in place on the rotating shaft by its inherent tension. The elastic sealing lip runs against an end wall and seals against dust, dirt, grease and other media. For the separation of several fluids, 2 seals can be installed, with the back against each other. The V-ring tolerates slightly eccentric or skewed shafts.
