Before introducing rectangular sealing rings, what are the characteristics of the standard sealing performance of rectangular sealing rings? Today, let's briefly talk about the main characteristics of the specifications and standards for rectangular sealing rings.

1、 Slow aging of materials

Unlike some sealing materials, rubber will gradually age naturally under pressure, that is, under stress, thereby reducing its elasticity. So the use of rectangular sealing rings has a certain lifespan and is closely related to the quality of the sealing material. Due to the small compression after installation, the aging rate of IBG seals is relatively slow.

2、 Good job stability

Due to the shape characteristics of the rectangular sealing ring, it will not twist after installation and has a small amount of deformation after compression; When the hydraulic pressure changes, the shaping is also relatively small. Therefore, the cross-sectional stability of the sealing ring is good.

3、 Good working sealing performance

When using a rectangular sealing ring, in the event of pressure shock, due to its geometric shape, there will be no fluid flow, let alone discharge due to movement. In terms of pressure performance, the rated pressure of rectangular sealing rings is 50MPa.

4、 Strong anti extrusion performance

5、 High sealing pressure

The working pressure of the seal is 32MPa, and the working pressure of the rectangular seal ring is 50MPa. When an O-ring is used for radial sealing and the pressure exceeds 10MPa, a retaining ring needs to be added on the low-pressure side to prevent extrusion damage. When using a rectangular ring, there is no need to set a retaining ring.

6、 Interchangeability

Seals of corresponding specifications can be installed in the original groove of the O-ring. So, it has good interchangeability with O-rings.
