What is an O Ring?

An O ring or rubber O ring is basically a round-shaped mechanical gasket. Patented in 1896, it is ideal for sealing and packing. It also prevents the passage of gases and liquids. Moreover, the design of O ring play an important role. It can be compressed to provide better sealing. 

O rings are small parts of big machinery. However, one cannot underestimate the importance of this product. Even the smallest seals can handle high amount of pressure. Therefore, it is also one of the vital sealing products.
