O-ring, also known as a packing or a toric joint, is a kind of round rubber ring which prevents the leakage of lubricating oil or foreign matters. As one of the most common seals used in machine design, it is widely used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring.

Best performance-to-cost values

◆ With good sealing performance under the working pressure and a certain temperature range, the O-ring can

     automatically improve the sealing performance under the increasing pressure.

 Very small friction between the O-ring device and the moving parts, and stable friction coefficient.

◆ Strong corrosion resistance, lowest aging, long service life, good wear resistance

◆ Self compensation to some extent after wear and tear.



O-ring is mainly used in the field of electronics, industrial machinery and equipment, telecommunications, medical equipment and other industries as below:

NBR O-ring is an ideal choice for aerospace, automotive, propane and natural gas applications.

Fluoro rubber O-ring is suitable for aircraft engines, automotive fuel handling systems, and chemical processing industries.

Silicon rubber O-ring is popular in food and medical applications because they are very clean and do not impart odor or taste.
