What is a Labyrinth Seal? - wiseGEEK

Mary McMahon Man with a drill . A labyrinth seal is a seal which creates a complicated path for liquids to pass through, making it challenging for liquids to cross the barrier created by the seal because they have difficulty making their way all the way through the labyrinth. These types of seals are used in a variety of settings, and can be used on objects which rotate and otherwise move.
