In addition to their durability, metal oil seals also offer excellent sealing capabilities, helping to prevent the escape of oil and other fluids from equipment. This is crucial for maintaining the proper lubrication of moving parts and ensuring that machinery operates efficiently. By creating a tight seal between mating surfaces, metal oil seals help to reduce friction and wear, extending the lifespan of components and reducing the need for maintenance.

The design must be such that it balances the need for a tight seal with the amount of friction generated during operation. Excessive friction can lead to wear and heat buildup, while insufficient sealing can allow fluid leakage. Therefore, engineers carefully select materials and dimensions to ensure optimal performance.

Demand dynamics also play a significant role in the pricing of oil seals. As global industries recover from economic downturns, the demand for machinery and vehicles tends to rise. This increased demand for oil seals can lead to higher prices if supply cannot keep pace. For example, during the economic recovery following the COVID-19 pandemic, many industries saw a surge in demand for automotive parts, including oil seals, straining the supply chains and driving prices upward. Moreover, the increasing trend toward electric vehicles, while potentially reducing some demand for traditional oil seals, has sparked interest in specialized seals for new technologies, which can also influence market prices.
