O-ring is a kind of rubber sealing ring with circular cross-section. Because its cross-section is O-ring, it is called O-ring, also called O-ring. It began to appear in the middle of nineteenth Century when it was used as a sealing element for steam turbine cylinders.

O-ring HZB253-640-02-01 is suitable for installing on various mechanical equipment, in the prescribed temperature, pressure, as well as different liquid and gas media, in the static or moving state to play a sealing role. Various types of sealing elements are widely used 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 instruments. The O type seal ring is mainly used for static seal and reciprocating seal. For rotary motion seal, it is only limited to low speed rotary seal device. The O type seal ring is usually installed in the groove of the outer circle or the inner circle, and has a sealing function in the rectangular groove. O-ring still plays a good sealing and shock absorption role in oil resistance, acid-base, grinding, chemical erosion and other environments. Therefore, the O type seal ring is the most widely used seal in hydraulic and pneumatic transmission systems.
