Oil seals are generally constructed from materials that can withstand the specific chemical properties of the lubricant they are sealing. Common materials include rubber, silicone, and various elastomers. The design of an oil seal often incorporates a lip that rolls against a shaft or surface, creating a dynamic seal that can accommodate movement while maintaining its sealing capabilities.

Another critical benefit of a well-designed OEM seal strip is noise reduction. Vehicle doors are often a source of unwanted noise from outside—be it wind, traffic, or environmental sounds. The seal strip dampens these noises, resulting in a quieter cabin experience. This is particularly important for luxury vehicles, where a serene driving environment is a key selling point.
