In any hydraulic cylinder there are multiple seals which is used for piston movement or the rod sealing. Here I am telling about the difference between rod sea and piston seal which is a type of U cup seal. So by watching this video you can easily identify the difference between rods seal and piston seal. Basically here I'm telling about asymmetric seals because if you will use piston seal in place of rod seal then you are effectiveness of sealing will not be good and the life of seal also will not achieve.
So watch this video and gain some knowledge out of it and use at your workplace.
I'm always thankful to you for your love and support to make India's skill and global skill.
