An O Rings are a mechanical gasket in the shape of a torus and also known as a packing or Toric joint. A rubber O-Ring is a loop of elastomer (polymer with viscoelasticity) with a round cross-section intended to be seated in a groove and squeezed together during assembling between two or more parts.
The Rubber O Rings are utilized in dynamic applications or in static applications where there is relative motion between the parts as well as the O ring. A static seal is where it doesn’t move and is used simply for maintaining a vacuum or containing pressure. Dynamic seals can be reacting. O-Rings are one of the largest common seals utilized in machine design because they are reasonably priced, easy to make, trustworthy, and have simple mounting requirements. It is mostly used in every field of industry including automotive, aerospace or general engineering.
