O-ring
Standard size
O-rings are suitable for being installed on various mechanical equipment, under the specified temperature, pressure, and different liquid and gaseous media, to play a sealing role in static or moving states. Various types of seals are widely used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, construction machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and various instruments and meters. element.
1. Suitable for a variety of sealing forms: static sealing, dynamic sealing.
2. Suitable for all kinds of materials, the dimensions and grooves have been standardized, and the interchangeability is strong.
3. Suitable for a variety of motion modes: rotary motion, axial reciprocating motion or combined motion (such as rotary reciprocating combined motion).
4. Suitable for a variety of different sealing media: oil, water, gas, chemical media or other mixed media.
5. Through the selection of suitable rubber materials and appropriate formula design, the effective sealing effect on oil, water, air, gas and various chemical media can be realized.

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 |
