An oil seal, also known as a lip seal or rotary seal, is a device used to seal the junction between stationary and moving parts in machinery. Its primary function is to prevent the leakage of lubricants, such as oil or grease, while simultaneously barring dirt and contaminants from entering the system. This is crucial for maintaining the efficiency and longevity of mechanical components.

One of the primary factors affecting the price of oil seals is the cost of raw materials. Oil seals are typically made from rubber, polyurethane, or various composites that provide flexibility, durability, and resistance to wear and temperature fluctuations. The prices of these materials can fluctuate based on global supply and demand, energy costs, and geopolitical events. For instance, an increase in the price of crude oil—often a precursor to escalating rubber prices—can lead to higher costs for oil seal manufacturers. Conversely, a decrease in raw material prices could result in lower prices for consumers.
