WebOur comparison assumes a cost of $10 for two lip seals (with 4 changes per year) vs. $300 for two rotating labyrinth seals (with one change every 4 years); in each case, the cost of maintenance labor would be $500 per event. Lip seal replacements would cost ($10+$500)*4 =$2,040 per year, or $8,160 over 4 years. WebLabyrinth Seals (a.k.a. Leidenfrost Seals or Mini Maze) have maze-like peaks that form between the inner and outer rings. This unique design keeps contaminants out and ensures the inner and outer rings of the seal stay inseparable.
