I have the Dupla Armatur Regulator, Yes the outlet valve ( Knurled valve )
does act this way especially when you have temperature swings. I ended up
getting NV-55 needle valves in order to control the bubbles per second.

and seems to be >nonadjustable.

This is true the regulator is non adjustable.


>Cannot fine any leaks please help !!!!!!!!!!!!!!!.
>can a gauge be fitted to this Dupla Armatur (Dupla Regulator ) so I can
tell how much co2 is in the bottle.


You have no leaks.
I have fitted a gauge to this regulator, But it shows you the pre calibrated
output pressure which is about 1.2 kg/cm2, and not the bottle pressure.
You'll have to unscrew the countersunk allen screw on the top of the
regulator cylinder and fit your gauge there.
