The 90% part signifies the sealing effectiveness. An ideal oil seal should ideally prevent 90% or more of the lubricant from escaping, while also preventing contaminants from entering the system. Advanced designs, such as labyrinth seals or double lip seals, enhance this percentage by creating multiple barriers, improving the seal's ability to protect the internal components from damage Advanced designs, such as labyrinth seals or double lip seals, enhance this percentage by creating multiple barriers, improving the seal's ability to protect the internal components from damage

The design must be such that it balances the need for a tight seal with the amount of friction generated during operation. Excessive friction can lead to wear and heat buildup, while insufficient sealing can allow fluid leakage. Therefore, engineers carefully select materials and dimensions to ensure optimal performance.
