O-rings are suitable for use in various mechanical equipment, providing a sealing function under specified temperatures, pressures, and different liquid and gas media, whether stationary or in motion. They are widely used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastics machinery, agricultural machinery, and various instruments and meters.
O-rings are primarily used for static and reciprocating motion sealing. When used for rotary motion sealing, they are limited to low-speed rotary sealing devices. O-rings are generally installed in rectangular grooves on the outer or inner circumference of the ring for sealing. O-rings maintain good sealing and vibration damping properties even in environments resistant to oil, acids, alkalis, abrasion, and chemical corrosion. Therefore, O-rings are one of the most widely used sealing components in hydraulic and pneumatic transmission systems.
