　　TC oil seals, also known as skeleton oil seals, are rubber completely covered double-lip oil seals with a self-tightening spring. They are commonly used to isolate the parts that need lubrication in the transmission part from the output part to prevent lubrication oil leakage 1.

　　There are several materials that can be used to make TC oil seals, including Nitrile Rubber (NBR), Fluorine Rubber (FKM), and Silicone Rubber. NBR is a common material for TC oil seals due to its good resistance to mineral oil-based hydraulic fluids, water, and air. FKM is known for its excellent heat resistance and chemical resistance, making it suitable for use in high-temperature and harsh chemical environments. Silicone Rubber is also used for its good heat resistance and non-toxicity.

　　When selecting the best material for TC oil seals, it is important to consider factors such as the application’s exposure to water, oil, gas, harsh chemicals or other materials; the minimum and maximum temperature resistances; the required compression strength; and whether the application will be exposed to sunlight for hours at a time.

　　There is no single “best” material for TC oil seals. The best material for a particular application will depend on the specific requirements of that application. It is important to carefully evaluate all of the available options and choose the material that will provide the best performance and durability.
