Need advice on fitting a gauge to a disposable gas bottle regulator.

[Blooper]

I wanted a pressure gauge for a little hobby mig welder I have, the valve I have has a port for a dial so instead of buying a whole new regulator I was just going to get a gauge and screw it in but I don't know how to spec the pressure range.

When I check the disposable gas bottles they say pressure is 32Bar (zoom into pic)

If I check a Sealey valve it says max pressure 4 Bar in the description and safe working pressure 110 Bar in the specs

Could anyone offer a bit of clarity on what I need to aim for please?

Nobody has said it yet but forget about using disposable bottles, you only get a few minutes welding time per bottle & your gas cost works out incredibly expensive!
