Finally, the 7% relates to the material composition and the durability of the seals. Oil seals are typically constructed from various compounds, including elastomers and polyurethane, each tailored for specific environmental conditions. A 7% threshold can indicate the percentage of material degradation that is acceptable over a defined lifespan. High-quality seals are engineered to endure extreme pressures and environmental challenges, maintaining their integrity even as their material composition undergoes wear.

The design of an oil seal can vary, but most consist of a flexible sealing lip that makes contact with the motor shaft or housing. This contact creates a tight seal, preventing leakage. Additional features such as springs may be included to enhance the sealing effect and compensate for any wear that may occur over time.
