I am not familiar with your valve. I use a separate fill set-up that has a hose and a vent valve built in. Some tank valves will (or should) vent when the valve is turned fully off.

It is, as you found out, VERY difficult to unscrew a pressurized connection. It can also be dangerous due to sudden release of pressure.

Can you show a picture of your tank valve? Maybe someone on the forum that is familiar with that valve can help.

I have never run into this issue with either my fwb pistol or rifle. I use a very tiny amount of the fwb grease that they recommend on the threads of the tanks. That works for me and I can unscrew partially and dry fire. I have been doing this for years.
The fwb grease is very expensive but one little tube is a lifetime supply. However, I find it difficult to believe that this issue is due to the use of the "wrong" grease.

Sorry, my friend, I actually have no idea why this is troubling you unless it is an issue with threads in your gun.

I hope someone smarter than me can answer your question; fwb 44 is a fine pistol fully capable of winning the Olympics.

I cannot imagine why fwb would change the fitting of the cylinders. There are many p44 on the firing lines and changing cylinder fitment is just stupid. I never thought that this could be an issue! As far as I know the difference in the 44 AND 8x is mostly cosmetic.

Unscrew! With just 85bar of air is easier

No, there's something else going on here. All FWB air cylinders from P30 up to P8X have the same threads, and are compatible all the way from old to new.
But a side note, when you screw the cylinder on the gun, just screw it in until it stops, and do not tighten it up hard. If you tighten it up hard, the air cylinder becomes pretty hard to unscrew as the pressure in the air cylinder drops.

I took it to a turner who straightened the threads and passed copper grease! I have a spray of these and now is perfect, smooth and perfect!
