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.

Beyond aesthetics, blue asphalt roof shingles are made from fiberglass or organic materials that provide robust durability. They are designed to withstand various weather conditions, including high winds, heavy rain, and ultraviolet (UV) radiation. Most asphalt shingles come with a warranty that promises longevity, often lasting 20 to 30 years with proper care. The protective granules embedded in the shingles also help reflect sunlight, contributing to energy efficiency by reducing cooling costs in warmer climates.
