Oil seals work by creating a tight seal around the rotating shaft. This prevents oil and other fluids from escaping while allowing the shaft to rotate smoothly. The seal is usually made up of a lip that fits snugly against the shaft, preventing any leaks from occurring. Some oil seals also have additional features, such as springs or gaskets, to provide extra support and ensure a secure fit.

Drain covers also play a significant role in environmental management. Urban drainage systems are designed to handle stormwater runoff, which can carry pollutants from the streets into waterways. By lifting drain covers, maintenance crews can access and clean out any debris that may block the flow of water. This is essential not only for preventing flooding but also for safeguarding local ecosystems. Clean drains help to ensure that water flows freely and that harmful contaminants do not enter rivers and lakes, where they can disrupt aquatic life.
