A V-Ring is a solid rubber seal used on shafts to prevent dirt, moisture, and other unwanted material from entering an oil seal, housing, or any other desired area while simultaneously keeping lubricants in. It works by stretching over the shaft to create a tight seal along the shaft while the flexible lip seals lightly against the counterface at a right angle to the shaft.

The V-ring works well on its own and excels when combined with rotary shaft seals and helps extend the life of bearings, oil seals, and shafts.
