In order to prevent the O-ring from twisting and damage, the following points should be paid attention to when designing. Follow the editor of EPDM oxygen O-ring price china for a simple understanding!
1. The concentricity of the O-ring installation groove should be considered from two aspects: ease of processing and no distortion.
2. The cross-sectional dimension of the O-ring should be uniform, and lubricating oil or grease should be applied to the sealing part every time it is installed. Sometimes a felt ring type lubricating device impregnated with lubricating oil can also be used.

3. Increase the cross-sectional diameter of the O-ring. The cross-sectional diameter of the O-ring for dynamic sealing should generally be larger than that for the static sealing. In addition, the O-ring should be avoided as a seal for large-diameter pistons.
4. When twisting damage occurs under low pressure, a sealing ring can be used to protect the retaining ring.
5. Reduce the surface roughness of the cylinder barrel and piston rod.
6. The O-ring seal is made of materials with low friction coefficient.
7. The O-ring can be replaced by a sealing ring that is not prone to distortion.
To sum up, the editor of EPDM oxygen O-ring price china tells: some small knowledge about O-ring design.
