The sealing effect of O-ring

The O-ring still plays a good sealing and shock absorption role in environments such as oil resistance, acid and alkali resistance, abrasion, and chemical erosion. Therefore, the O-ring is the most widely used seal in hydraulic and pneumatic transmission systems.

The O-ring has its own sealing function and does not undergo periodic adjustments. When used for sliding sealing, the sealing performance is not affected by the direction of movement, and it is small in size and convenient to use. Due to its adaptability, the sealing ring has a wide range of applications, but it is prone to deformation when the pressure peak reaches a certain pressure, which may cause the possibility of squeezing out gaps. It is widely used in aviation and hydraulic engineering.
