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 significant benefit of these shingles is their low maintenance requirements. Unlike natural wood, asphalt shingles do not require periodic sealing or staining. They are also resistant to rot, insect damage, and harsh weather conditions, such as heavy rain, snow, and high winds. This resilience means homeowners can enjoy the beautiful appearance of cedar shakes without the time-consuming upkeep associated with genuine wood.
