50/5076 valve stem seal, support OEM customized size, sample service

Short Description:

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

Specification

Valve oil seal

OE standard size

Stem oil seal

Valve stem 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

Advantages of oil seals:

Good surface gloss, good elasticity, excellent sealing effect, good weather resistance, good material stability, customized non-standard models, mature technology, stable quality

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
