hey i have a fairly new fire extinguisher that would be a great air tank for a current project but how can i make an air tight seal in connecting it to standard piping? when i screw in 3/4 inch galvanized piping it only goes an 1/8 th of an inch deep before getting stuck and askew. im sure this has already been asked but i would appreciate the help.

What brand and model?
Pictures?

What thread is your 3/4 pipe? NPT. BSPT, BSPP

If you have caliper, measure ID of extinquisher thread.

Here is example of extinquisher as chamber.
