omega 18 cu ft tank with new hp3 valve issues

I've tried using this tank several times
Last time my new hatson pistol I just got
First fill. Pow instant 300 in the tank and gun
2 O rings gone.
Quicker that you blink your eye regardless how gently
You feather the valve if that's the way it operates then I will pass
My hatsan and ninja valves work flawless
So I just bought a 3l allsafe tank m18x1.5
74 cu ft I. Going to use the hatsan reg
Works flawless I. An creep the air slow
Just like the ninja and don't need to open and close the valve when filling
Plug it.in plug it in and go.
