Classification of O-rings
The classification of rubber O-rings mainly includes UHSO-rings, UHPO-rings, UNO-rings, DHO-rings, piston rod O-rings, high-temperature O-rings, high-pressure O-rings, corrosion-resistant O-rings, wear-resistant O-rings Damaged O-rings. It is suitable for being installed on various mechanical equipment, under the specified temperature, pressure, and in different liquid and gas media, it can play a sealing role in static or moving state. Various types of sealing elements are widely used in sanitary ware, ships, automobiles, hardware, electronics, toys, electrical appliances, machinery, and various instruments and meters. Rubber O-rings are mainly used for static sealing and reciprocating sealing. When used for rotary motion seals, it is limited to low-speed rotary seals. The rubber O-ring is generally installed in the groove with a rectangular cross-section on the outer or inner circle to play a sealing role. Rubber O-rings still play a good role in sealing and shock absorption in environments such as oil resistance, acid and alkali resistance, grinding, and chemical erosion. Therefore, the rubber O-ring is a widely used seal in hydraulic and pneumatic transmission systems.
O-ring advantages
1. Simple structure, small volume and compact installation location.
2. It has the function of self-sealing, no need for periodic adjustment.
3. Good sealing performance, no leakage during static sealing.
4. The frictional resistance of movement is small, which is suitable for occasions with alternating pressure.
5. The size and groove have been standardized, the price is cheap, the product is easy to obtain, and it is easy to use and purchase.
6. Strong adaptability and wide range of uses.

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 |
