The only thing that happens to orings is they become flat instead of round.

Get new orings since you ruined the old ones.
Relax , I didnt sand them that much , they are still round. And DVs are equally functioning like they should now.

Yes , sanding them might not be any point , but sanding that little should not make any negative result on the O-rings , I only used 800 paper. You can see in my video that valve is operating when vacuum is applied. If I ruined anything they would not hold vacuum.

And new O-rings from Forge is 10$ with new piston . And I only need O-rings , they are 2$.
