Scope of application of O-ring

O-ring seals are suitable for installation on various mechanical equipments, and play a sealing role in static or moving state under the specified temperature, pressure, and different liquid and gas media. 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 types of instruments, various types of seals are widely used element. O-rings are mainly used for static sealing and rotary motion sealing. When used for rotary motion sealing, it is limited to low-speed rotary sealing devices. O-rings are generally installed in grooves with a rectangular cross-section on the outer or inner circle for sealing. O-rings are resistant to oil and acids. Therefore, O-rings are the most widely used seals in hydraulic and pneumatic transmission systems.
