I can't tell from here, but most of the small "spray paint" cans have the same tops on them. I believe they are 5/16 fittings. 99.9% of the stuff they sell at the HVAC store (Johnstone, United, etc.) has 1/4 inch flare aka acme or the same thing as nitrogen cylinders. The old R12 and R22 "spray" cans had 1/4 inch fittings on them, and when the industry mothballed CFC refrigerants, that's when all of the standards changed. Now you never know what type of fitting is going to be needed until you see it. Even the old fridgie techs carry a universal "fits all" adapter set in their bag. Cuz it sucks when the specs lie.
