Scope of application of O-ring

Scope of application of O-ring

O-ring is applicable to be installed on various mechanical equipment, and plays a sealing role in static or moving state at specified temperature, pressure, and different liquid and gas media.

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 seal, it is limited to low-speed rotary seal device. The O-ring is generally installed in the groove with rectangular section on the outer circle or inner circle for sealing. The O-ring still plays a good sealing and shock absorption role in the environment of oil resistance, acid and alkali resistance, grinding, chemical corrosion, etc. Therefore, O-ring is the most widely used seal in hydraulic and pneumatic transmission systems.

Advantages of O-ring

Advantages of O-ring VS other types of seals:

–Suitable for various sealing forms: static sealing and dynamic sealing

–Suitable for multiple motion modes: rotary motion, axial reciprocating motion or combined motion (such as rotary reciprocating combined motion)

–Suitable for various sealing media: oil, water, gas, chemical media or other mixed media

Through the selection of appropriate rubber materials and appropriate formula design, it can effectively seal oil, water, air, gas and various chemical media. The temperature can be used in a wide range (- 60 ℃~+220 ℃), and the pressure can reach 1500Kg/cm2 (used together with the reinforcing ring) during fixed use.

–Simple design, compact structure, convenient assembly and disassembly

–Many kinds of materials

It can be selected according to different fluids: NBR, FKM, VMQ, EPDM, CR, BU, PTFE, NR
