Do you still have the original plug that came with the fire extinguisher?

take it to a hardware store and just test witch fitting fits best, my one was very close to 1/2'' bsp so i just epoxied a 1/2 male fitting in there.

i have tested it to 600psi/41 bar

The pipe that reaches from the plug to the bottom of the fe is screwed into it, try if a fitting fits with the threads. If so, cut away the original release valve from the plug and screw the fitting into it from the top.

It worked with my fire extinguisher but there will be some bottlenecking due to the smaller fitting.

Hi!this is my first post.
I have the same fire estinguisher,made from ANAF Group,a french company,
i'm from italy but the product is the same.
During my research i've found that the connection is metrical iso,M30x1,5,you (we) need to find an adapter,from metrical to gas,like this http://www.oleodinamica.org/gas-metrico2.pdf

That what I did :P And it worked out fine, but I only used to 20 bar as the bottle won't take more :( still looking for a 2L CO2 tank :) .
