Valve Stem Seal

The valve stem seal is one of the valve seals of the engine. NIYOK valve stem seal adopts a low-friction design, can withstand the high pressure of the engine exhaust and intake to improve the emission quality and improve the efficiency of the engine. The spring can ensure a long time on the quality of the seal. Our new rubber material can withstand even the most corrosive oils on the market. It is the most common part in the aftermarket and the valve stem seal is generally made by co-vulcanization of the outer frame and fluorine rubber. The aperture is equipped with a self-tightening spring or steel wire, which is used to seal the engine valve guide rod, which is one of many oil seals for cars and motorcycles.

Because the working environment of the valve oil seal is at high temperature and high pressure, it is necessary to use materials with excellent heat resistance and oil resistance. The commonly used materials for oil seals are NBR, FKM, Silicone, ACM, polyurethane, polytetrafluoroethylene.

The Function of Valve Stem Seal

Valve Stem Seal can prevent leakage and pressure in the engine and maintain normal pressure. It also can prevent engine oil from entering the combustion chamber and avoid engine oil loss. The valve stem seal is one of the important parts of the entire engine. It is usually in contact with gasoline and engine oil at high temperatures, therefore, heat-resistant, and oil-resistant rubber materials are required, so Fluorine rubber is a common choice.
