Valve seal

Valve stem seal is a kind of oil seal, which is generally formed by external skeleton and fluororubber co-vulcanization. The oil seal diameter mouth part is equipped with self-tightening spring or steel wire, used for the sealing of engine valve guide rod.

The valve oil seal can prevent the oil from entering the intake and exhaust pipes to prevent the loss of oil, prevent the mixture of gasoline and air and exhaust gas from leaking, and prevent the engine oil from entering the combustion chamber. Valve oil seal is one of the important components of the engine valve group. It is in contact with gasoline and engine oil at high temperatures. Therefore, it is necessary to use materials that are excellent in heat resistance and oil resistance, and generally made of fluororubber.
