Valve Stem Seals are used in car engines which can control the leak rate of engine oil to lubricate the valve stem and guide. Besides, valve stem seals can prevent engine oil from flowing into exhaust pipe and intake pipe and to avoid engine oil entering into combustion chamber.

Valve stem seals provide the proper amount of oil to the valve stem interface of an internal combustion engine, lubricate the valve guides, and reduce engine emissions. They can be used in diesel and petrol engines with or without supercharging

Valve stem seals control the lubrication of the valve stem as it slides in the valve guide. Too little oil causes stem and guide wear. Too much oil increases oil consumption and can cause a buildup of carbon, leading to valve seat damage and an early valve grind. Faulty valve stem seals increase oil consumption.Valve stem seals provide a defined metering rate of oil to the valve stem interface of internal combustion engines to lubricate the valve guide and minimize engine emissions. They are available for diesel and gasoline engines with and without boosting.

Valve stem seals are made from a variety of materials, including nylon, PTFE rubber, steel, and synthetic rubber. Sometimes these materials are combined into a single sophisticated design. When synthetic rubber is used, there are three basic types: nitrile, polyacrylate, and Viton.

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.

FAQ

Why use oil seals?

1、Origin of oil seal

Oil seals, also known as shaft seals, because hydraulic cylinders, gearboxes and other related components have always had the problem of oil and grease and other media leaking along the rotating shaft.The oil seal came into being.

2、The role of the oil seal

Oil seals are used to close the space between stationary and moving parts in machinery and also help prevent lubricants from escaping the system. Prevent pollutants from entering in harsh working environment of high temperature and high pressure.

3、Oil seal structure

The oil seal is generally composed of three basic components: sealing element, metal shell and clamping spring.Types of oil seals include single and double lips, rubber or polymer, metal housing, spring loaded, and internal, external and axial guides.
