O-rings produced from rubber materials are collectively referred to as rubber O-rings. Its main function is to seal, with excellent sealing performance and high working life. The working life of dynamic pressure seal is 5-10 times higher than that of conventional rubber seal products, and the maximum life can be dozens of times. Under certain conditions, it can have the same life as the sealing base.
1. O-rings are the components of choice for many manufacturers; not only because of their relatively low cost to manufacture, but also because of their myriad other benefits.
2. O-rings can form seals over a wide range of temperature, pressure and tolerance levels. They do not require any critical torque when tightening and are therefore less likely to cause damage to the structure.
3. The O-ring naturally returns to its original shape when pressure is applied to the cross section, so it has been proven to be very reliable and strong.

|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
|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
