Yellow Silicone FKM NBR Molding Rubber O rings O-ring Seal
O Ring Seal Product Description
The O-Ring is one of the most basic and functional seals ever made and is the backbone to all the hydraulic and sealing applications in the world. An O-Ring is a solid-rubber seal shaped like a dough nut or torus. When compressed between mating surfaces, an O-Ring blocks the passage of liquids or gases. O-Rings are available in a wide range of standard and non-standard sizes that are suitable for nearly all sealing applications.

| Material | NBR(Nitrile Rubber ( Buna )) |
| Advantage | 1.Excellent oil resistance
2.Hydrolytic resistance
3.Excellent wear resistance
4.Good air tightness
5.Excellent antistatic properties
6.Resistant to alcohol |
| Disadvantage | 1.Poor cold resistance
2.Not resistant to ozone |
| Temperature | 54℃~135℃ |
| Application | NBR is mainly used to manufacture oil resistant rubber products |
NBR is mainly used to manufacture oil resistant rubber products. Acrylonitrile content in nitrile butadiene rubber (%) has 42 ~ 46, 36 ~ 41, 31 ~ 35, 25 ~ 30, 18 ~ 24 and other five kinds. The more acrylonitrile content, the better oil resistance, but cold resistance is decreased. It can be used in 120℃ air or 150℃ oil for a long time. In addition, it also has good water resistance, air tightness and excellent bonding properties. It is widely used to produce all kinds of oil-resistant rubber products, a variety of oil-resistant gaskets, gaskets, bushing, flexible packaging, flexible hose, printing and dyeing roller, cable adhesive materials, etc. It has become an indispensable elastic material in automobile, aviation, petroleum, photocopying and other industries.
