Oil seals can be made from various materials, including rubber, silicone, and polyurethane. The choice of material often depends on the operating conditions such as temperature, pressure, and the type of lubricant being used. For the 50x65x8 oil seal, nitrile rubber (NBR) is commonly utilized due to its excellent oil resistance and durability in a range of temperatures.

Market demand significantly influences oil seal prices. In periods of high demand, such as when automotive or aerospace industries experience growth, the price of oil seals can rise. The global push towards electric vehicles (EVs) and advanced machinery can increase the demand for high-performance oil seals, contributing to price variations. Conversely, in times of economic downturn or decline in manufacturing output, demand may decrease, leading to price reductions.

3. Pressure Maintenance In many applications, oil seals are designed to maintain pressure within a system. By preventing the exit of oil and the entrance of contaminants, they help in sustaining the necessary pressure levels for optimal operation. This function is especially important in hydraulic systems, where pressure plays a critical role in performance.
