What is an O-ring? Which form of sealing is it suitable for?

O-ring is a common seal, its cross-section shape is round, hence the name. It is made of elastic materials, usually rubber or silicone materials, with good elasticity and self-sealing performance. O-rings are suitable for many forms of sealing, including static and dynamic sealing.


In a static seal, O-rings are placed between two parallel planes, such as pipe joints or between valve seats. When subjected to compression load, the O-ring deforms and fits tightly onto the sealing surface, forming an effective seal. The elasticity and self-sealing performance of O-ring make it have better effect in static sealing.


In dynamic seals, O-rings are usually mounted on the surface of the shaft or hole to prevent the leakage of liquid or gas. In the process of movement, the O-ring is subjected to shear force and will have a certain deformation. But over time, the O-ring will gradually adapt to the surface of the shaft or hole, forming an effective seal.


O-rings are suitable for a variety of industries and fields, including machinery, chemicals, oil and gas, etc. In these industries, O-rings are widely used in the sealing of various pipes, valves, hydraulic systems and other equipment.


In short, O-rings are a common seal suitable for many forms of sealing. It has good elasticity and self-sealing performance, which can effectively prevent the leakage of liquids and gases. It is widely used in various industries.
