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.

In addition to the materials used, the design of high temperature shaft seals is also crucial for their performance. The seal must effectively block the passage of fluids or gases through the interface between the moving shaft and stationary housing. This requires precise engineering to ensure a tight fit and proper sealing under varying temperature and pressure conditions.
