The DC oil seal profile consists of a single metal cage with rubber coating and a dual main sealing lip with integrated springs. This unique design enables seals to effectively separate fluids, making it an ideal choice for applications that require the separation of two fluids.     
The metal retainer of DC oil seals           is usually made of steel, providing structural integrity and resistance to high pressure and high temperature for the seal. The rubber coating enhances the sealing ability of the seal at the outer shell and is suitable for softer materials. The main sealing lip of the DC oil seal is integrated with the spring and is usually made of standard carbon steel. The spring ensures constant contact between the sealing lip and the shaft, thereby improving the sealing effect.     
The rubber used in DC seals can be made of various materials, including NBR (nitrile rubber), FKM (fluororubber), etc. These materials have different characteristics and are suitable for different applications. For example, NBR is known for its excellent oil resistance, while FKM has excellent heat resistance.     
In cars, the most common use of oil seals           is to prevent lubricating oil leaks from the engine and transmission. In addition, it is also used for sealing parts such as car wheels, air conditioning compressors, and steering gears.
