Valve stem seal is a kind of oil seal, which is generally formed by vulcanizing outer frame and fluororubber together. Self-tightening spring or steel wire is installed at the radial opening of the oil seal for sealing engine valve guide rod.  The valve oil seal can prevent oil from entering the intake and exhaust pipes, causing oil loss, preventing the gas mixture of gasoline and air and exhaust gas from leaking, and preventing engine oil from entering the combustion chamber.  Valve oil seal is one of the important parts of engine valve group. It contacts with gasoline and engine oil at high temperature. Therefore, it needs to use materials with excellent heat resistance and oil resistance, usually made of fluororubber
