An O-ring is a type of static or dynamic sealing ring installed in grooves. Unlike many other seals that require special instruments for installation, it is easy to assemble into a function.

O-rings are the most versatile seals; they can provide axial or radial sealing solutions in nearly all applications to seal oil, water, air, gas and other fluids. They are widely utilized in various applications, anywhere from sophisticated home heating systems to automobile air-conditioning.
