What parts do I need to connect a Brno TAU 200 to a Ninja HPA tank?

Hello CGN airgun Gurus,

I recently picked up an older Brno TAU 200 PCP air rifle. The air cylinder has a male threaded end of unknown thread pitch. I have pulled the cylinder of the rifle and taken a couple of photos of it.

It also came with a small compressed air cylinder with the corresponding female threading so it will screw onto the end of the rifle to refill it.

Here's a photo of the end cap off the rifle threaded into the external bottle.

My Googlefu has not helped me find any technical data on the thread pitch.

I would like to be able to connect the rifle cylinder to my Ninja HPA fill station which has a 1/8" female quick connect.

Anyone know what the thread pitch on the BRNO rifle might be or know what part I need to make the connection between the rifle and quick disconnect?

Thanks

Your best bet would be to check out a compressor repair shop they may have a conversion fitting or at least know where to order one from.
 
If the threads are the same as the tau 7 you won’t find anything outside of a custom machined piece. It will be pricey but to do what you want will probably require a machinist.
The male threads are metric but I can’t find anything on pitch.

Also the “compressed air” cylinder you’re referring to is a co2 tank
