Application range of O-ring

O-ring is suitable for installation on all kinds of mechanical equipment, in the specified temperature, pressure, and different liquid and gas media, in the state of static or moving sealing. In machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and all kinds of instruments and meters, a large number of applications of various types of sealing components. O - ring is mainly used for static seal and reciprocating motion seal. For rotary motion seal, limited to low speed rotary seal device. O-type sealing ring is generally installed in the outer circle or the inner circle on the rectangular section of the groove to seal. O ring in oil, acid and alkali, wear, chemical erosion and other environments still play a good sealing, shock absorption role. Therefore, O-ring is the most widely used seal in hydraulic and pneumatic transmission system.

The advantages of the O-ring

Compared with other types of sealing rings, O-ring has the following advantages:

-- Suitable for a variety of sealing forms: static seal, dynamic seal

Suitable for all kinds of materials, sizes and grooves have been standardized, strong interchangeability

-- Suitable for a variety of motion modes: rotational motion, axial reciprocating motion or combined motion (such as rotary reciprocating combination motion)

-- Suitable for a variety of different sealing media: oil, water, gas, chemical or other mixed media

Through the selection of appropriate rubber materials and appropriate formula design, to realize the effective sealing effect of oil, water, air, gas and various chemical media. The temperature range is wide (-60 ℃ ~ + 220 ℃), and the pressure can reach 1500Kg/cm2 when fixed (and the reinforcing ring is used).
