Are you not using the standard large hand lever on the fire extinguisher as the filler valve ? As soon as you let go of that it shuts immediately. See the attached pic on my previous post. Are you using some other type of valve from the extinguisher ?Originally Posted by Katanga
Hello If I remove the adaptor from the Co2 fire extinguisher with the cylinder attached all the Co2 gas from the cylinder escape (the shut-off valve still open).
