Because of its O-shaped cross section, it is called an O-ring rubber sealing ring, also called an O-ring. It began to appear in the middle of the 19th century, when it was used as a sealing element for steam engine cylinders.

O-ring seals are suitable for installation on various mechanical equipment, and play a sealing role in static or moving states under specified temperature, pressure, and different liquid and gas media. 0.3mm-oring manufacturers tell you that in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and various instruments and meters, a large number of Various types of sealing elements are used. O-rings are mainly used for static sealing and reciprocating motion sealing. The 0.3mm-oring manufacturer tells you that when it is used for rotary motion sealing, it is limited to low-speed rotary sealing devices. The O-ring is generally installed in a groove with a rectangular cross-section on the outer circle or the inner circle to play a sealing role.
