O-ring
Standard size
O-ring has excellent sealing performance and long working life. The working life of dynamic pressure seal is 5-10 times higher than that of conventional rubber sealing products, and the maximum can reach dozens of times. Under certain conditions, it can have the same life as the sealing base.
1. The frictional resistance of the O-ring is small, and the dynamic and static frictional forces are equal, which is 1/2-1/4 of the frictional force of the "0"-shaped rubber ring, which can eliminate the "crawling" phenomenon of movement at low speed and low pressure.
2. The O-ring is highly wear-resistant, and has the function of automatic elastic compensation after the sealing surface is worn.
3. The O-ring has good self-lubricating properties. Can be used as oil-free lubrication seal.
4. The O-ring has a simple structure and is easy to install.

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 |
