Valve Stem Seal

Product Details: The valve stem seal is installed in the valve guide in the engine head to prevent engine oil from flowing into the combustion chamber through the valve stem and the sliding surface of the guide. It is made by co-vulcanization of the outer frame and fluorine rubber, equipped with a self-tightening spring or steel wire. The seal adopts a low-friction design to withstand high engine pressures and improve emission quality and engine efficiency. It ensures proper lubrication of the valve stem, reducing friction and wear between the valve stem and valve guide. The seal is designed to allow a small

amount of oil leakage to lubricate the sliding portion outside the seal.
