Type of Valve Stem Seals and Valve Seals

Valve Stem Seal

xtnbk supply professional and honest service.

Due to emissions laws, coupled with the fact that today's engines run hotter and valves open and close up to 100,000 times an hour, your stem seals have to be of good quality. NNK valve stem seals are made of the highest quality materials and the latest technology, ensuring tightness while extending service life and reducing replacement frequency.

 

The function of the valve stem seal

Valve stem seals are installed in the valve guides and slide to control valve stem lubrication. Too little oil can cause stem and guide wear. Too much oil can increase oil consumption and cause carbon deposits, which can lead to valve seat damage and premature valve wear. At the same time, if the valve stem seal is damaged, it will also increase the fuel consumption.

 

NNK valve stem seal design:

Positive seals : Attach to the valve guide boss. They work like a squeegee, wiping and metering oil on the stem as it passes through the seal.

Deflector seals: Deflect oil away from the valve stem. Also called umbrella seals, they move with the valve stem to shield the valve guide from excess oil.

Stem Seal Materials: Nylon, Teflon, Steel, and Synthetic Rubber (NBR, Polyacrylate, and Viton).

NNK and valve stem seals&#;

In order to prevent premature hardening and rupture due to insufficient heat resistance of rubber seals, NNK guarantees the service life and ensures that the engine is in a lubricated state. The materials we choose are based on the use environment of the seals and the characteristics of the materials themselves. The oil seals produced have high-quality properties such as high temperature resistance, wear resistance, and long service life. Currently, Viton has excellent heat resistance (up to 450° F) and abrasion resistance and is the material of choice for most valve stem seals. If you have any valve stem seal needs, please contact us.

Description

Valve Stem Seals are used in car engine, which is preventing engine oil enter to exhaust pipe, preventing gasoline mixed with air, and preventing engine oil enter to combustion chamber.

 

The valve stem seal is one of the valve seals of the engine. NNK 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.
