What is a car oil seal

Vehicle oil seals may be affected by wear and aging during use, leading to a decrease in Sealing performance. Therefore, regular inspection and replacement of vehicle oil seals is an important measure to maintain normal vehicle operation and extend the lifespan of components. If there are signs of liquid leakage in the vehicle, especially lubricating oil leakage, the relevant oil seals should be checked and replaced in a timely manner.

Vehicle Oil Seal is a sealing device used in automobiles and other motor vehicles to prevent the leakage of lubricating oil or other liquids from the moving parts of the vehicle. It is usually installed in parts such as the engine, transmission, wheel hub, transmission shaft, etc., playing a sealing and leak proof role.

Vehicle oil seals are usually made of elastic materials, such as rubber or polyurethane. It has a soft characteristic that can adapt to the rotation or oscillation of moving parts and maintain close contact with them. Vehicle oil seals typically consist of an inner ring, an outer ring, and a sealing lip.

The inner ring is the part that comes into direct contact with the moving parts, usually made of metal and has a certain fit gap with the moving parts. The outer ring is fixed to the vehicle's components, such as the engine housing or transmission shaft housing. The sealing lip is the rubber or polyurethane part that connects the inner and outer rings, which is in close contact with the moving parts and prevents liquid leakage.
