if possible, test a trial print for air tightness. A simple method to do this is install the fitting in place with a gas supply but block off the outlet with tape. Then apply liquid soap to the outside. If you see bubbles, the print is porous. Try changing the print settings (hotter, more extrusion) or apply an acetone or lacquer treatment. Ensure that any treatments are fully dry before retesting or use.
