Applications:

NBR/Silicone/FKM/EPDM/FPM O Ring is often used in the working environment that needs to resist of heat, chemical corrosion, oil, etc.

The o rings are widely used in metallurgy, chemical, automobile, mechanical and electric power industry.

The O-ring may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons.

O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, reliable, and have simple mounting requirements. They can seal tens of megapascals (thousands of psi) of pressure.


The O-ring is suitable to be installed on various mechanical equipment to seal at the specified temperature, pressure and different liquid and gas media in the static or moving state. 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 meters.
O-ring is mainly used for static seal and reciprocating seal. When used for rotary motion sealing, it is limited to low-speed rotary sealing device. The O-ring is generally installed in the groove with rectangular section on the outer circle or inner circle to seal. The O-ring still plays a good role in sealing and shock absorption in the environment of oil resistance,acid-base, wear, chemical erosion and so on. Therefore, O-ring is the most widely used seal in hydraulic and pneumatic transmission system.
