O-rings are rubber rings with an "O" shape in cross section. It is widely used in hydraulic and pneumatic transmission systems. It is mainly used to prevent the leakage of liquid and gaseous media under static conditions. In some cases, O-rings can also be used as dynamic sealing elements for axial reciprocating motion and low-speed rotary motion. Its simple structure, convenient installation, low cost, easy maintenance, and diverse materials. It can be used for sealing various fluids such as oil, water and gas. According to different conditions, different materials can be selected to suit them.
From the perspective of the sealing principle, the O-ring is a squeeze seal. The basic working principle of the squeeze seal is to rely on the elastic deformation of the seal to cause contact pressure on the sealing contact surface. The contact pressure is greater than that of the sealed medium. Internal pressure, no leakage occurs, and vice versa.
