I don't think it will work I think you will need to just try a different gun, I think the differince is in the guts of the gun not just the air cap. i could be wrong. I would try a small tip sizes, what are you spraying?? You might want to try a 1.2 tip, I use to use a 1.4 in my sata and then tried a 1.3 and liked it better, but depending on what you are spraying 1.2 might help
