Product Description

The valve stem seal can prevent oil from entering the intake and exhaust pipes, avoid oil loss, prevent the mixture of gasoline and air, and prevent engine oil from entering the combustion chamber. The valve oil seal is one of the important parts of the engine valve group, which is in contact with gasoline and oil at high temperature. The valve oil seal allows a small amount of oil to flow into the internal combustion engine, thereby ensuring the lubrication of the valve stem in the valve guide, improving the use time and function.Therefore, the valve stem seal is called a seal that controls the amount of oil.
