     The Valve stem seal is a very important part of the Auto Engines. It is installed at the top and/or end part of the valve tube which locates between the valve stem and the valve tubes. It can adapt to the changing gap between the stem and the pipe in the reciprocating movement, control the lubricating of oil flowing into the gap between the guide rod and the pipe, ensure the lubrication needs of the valve stem and the oil seal lip, and avoid the lubricating oil entering the cylinder through the gap. The valve stem seals can reduce the oil leakage into the combustion chamber causes the components to be charcoal and reduces the service life of the engine parts.
