FX Panthera Valve Rod Leak

Yes. In fact, it gave a millimeter adjustment. Tomorrow I'll check if it leaked or not. Thank you for the tip

Looks like the valve cap is loose which broke a oring on a panthera that I fixed seen it a few different times

it is the third time this problem has happened to me, the first time due to a shot with the rifle without pressure and the O-ring x1-2 broke, old version of the valve, the second time the same or O-ring broke without particular causes, and the third time I attach the photo, the valve is destroyed

the rifle is one year old, now I'm waiting for the cap, valve stem and seat

I would have stoned the back of the valve flat if that was all that was wrong with it it seals at the orings looks like the hammer kissed it

I degassed my Panthera to install a Huma regulator. I watched a YouTube and saw a guy dry firing to do this. Bad thing to do. Bent my valve rod which was the earlier skinny one.
Ordered the complete kit of valve and seat and o rings and seat removal tool. Still leaked so replaced all o rings again and have the leak reduced to a point that it takes 3 days to run out of pressure. Thinking about buying another valve and seat and trying again.
Any thoughts would be appreciated. Was thinking of selling the gun (25/700) but a leaking gun is not worth much

I found if you remove the return spring no more bending on the valve it bottoms out on the spring then they bend i remove the return spring on a 30 cal and turned then part of the valve down to .090 thousandths and it has been running strong with out any leaks or bending the worst part is getting it sealed for the first time

Some of the valves from the factory are not very straight to begin with
