Rubber O-ring is rubber ring with O-shaped cross section, it has high elasticity, insulation and long service life.O-ring kit is a complete set of rubber O-rings, which is generally used to repair .It is commonly used in machinery manufacturing, automotive, electrical, medical and other industries,and plays the role of sealing, insulation, cushioning, fixing, etc. Therefore, rubber O-ring is one of the most commonlyused seals in global machinery.
The most common material in the O-ring kit is NBR. Other materials like EPDM, SIL, FKM, ACM.
We should choose the appropriate material according to its use environment.
| Rubber | Characteristic | Application |
| NBR | Oil resistance | Oil tank, lubricating oil tank, mechanical equipment, use environment without special requirements |
| EPDM | Strong water and steam tightness | Water pump, bathroom, automobile brake system |
| SIL | Good elasticity, wide temperature range, wide practicability | Electronics, food and medical industry |
| FKM | High temperature resistance, chemical resistance | Automobile engine, fuel system, mechanical equipment of chemical plant |
| ACM | High temperature resistance (weaker than FKM) | Automobile engine, fuel system |
