Diesel Engine Parts Stem Seal 3921640

Short Description:

Valve oil seal is a kind of oil seal, which is generally made of outer skeleton and fluororubber co-vulcanized. The diameter of the oil seal is equipped with a self-tightening spring or steel wire, which is used to seal the engine valve guide rod. The valve oil seal can prevent oil from entering the intake and exhaust pipes, causing oil loss, preventing the leakage of gasoline and air mixture and exhaust gas, and preventing engine oil from entering the combustion chamber. Valve oil seal is one of the important parts of the engine valve group. It is in contact with gasoline and oil at high temperature. Therefore, it needs to use materials with excellent heat resistance and oil resistance, generally made of fluorine rubber.

Stem oil seal

Rod seals are used in automotive engines to control the leakage rate of engine oil to lubricate valve stems and guides. In addition, the valve stem seal prevents oil from flowing into the exhaust and intake pipes, preventing oil from entering the combustion chamber

material	Low TEMP.	High TEMP.	Performance
NBR	-40	120	Good resistance to alcohol,amines, petroleum oils, and gasoline over a wide range of temperature. Also good resistance to caustic salts and fair acid. Poor in strong oxidants, chlorinated hydrocarbons, ketones, and esters
HNBR	-25	140	HNBR is made from NBR by hydrogenation. It has high temperature resistance, abrasion resistance and good physical properties.
ACM	-25	150	It is used in diaphragm, hose for automotive application. Good resistance to heat, ozone and oil. Generally attacked by water, alcohol, glycol and aromatic hydrocarbons. The molecular structure contains ethyl acrylate (EA). Butyl acrylate (BA), and methoxy ethyl acrylate (MEA). High BA content get better low temperature resistance, and high MEA content get more oil resistance.
EPDM	-40	125	Stable in polar fluids (alcohol, ketone, and glycol), and hydrochloric acid. Due to the low specific gravity, it can compound with large amount filler.
VMQ	-60	125	The most widely temperature ranges for application. Good weather and ozone resistance, but poor mechanical property and chemical resistance.
FKM	-20	250	Fluoroelastomers have a high degree of chemical stability and are currently the best media resistance of any elastomer. Type 26 fluoroelastomer resistant to petroleum-based oils, diester oils, silicone ether oils, silicic acid oils, inorganic acids, most organic, inorganic solvents, drugs and so on
