An O-ring is a ring made of elastomer, or commonly referred to as rubber. The term O-ring literally identifies its circular section: 'O' for its shape and ring for being a ring. In Italian they are also called 'O-rings'.
Standard O-ring
Special O-rings
OR Rope
They are used as a mechanical seal or gasket and are designed to be inserted into special housings/seats. Orings are compressed during assembly of two or more parts, thus creating a seal.
The seat that houses the O-ring is a fundamental part of the sealing system, creating great influence on the efficiency of the system itself. The connection between the seat and the O-Ring itself can be static, when the parts do not move with respect to each other, or dynamic, when they do move. The surface finish of the O-Ring seat and all surfaces that come into contact with it is an important factor in the sealing capability and durability of the seal itself.
Dynamically sealed systems must have higher levels of precision and finish than statically sealed systems, as friction between parts accelerates the degradation of the O-ring. Increased lubrication is therefore required in joints with overheating due to friction.
The use of O-rings is also quite common due to their limited cost. They are simple elements and the main use of O-rings is as sealing elements in joints in hydraulic and pneumatic systems, preventing/limiting fluid leakage.
