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.

Public safety is another critical consideration. Poorly maintained or damaged gully covers can pose serious hazards. Individuals can trip or fall into open gullies, leading to injuries. Additionally, if a cover is dislodged due to heavy rainfall or improper installation, it can create hazardous conditions. Therefore, communities must implement regular inspections and maintenance of drainage gully covers to ensure that they are in good working condition and safe for public use.
