I meant to get a straight (non-coiled) hose but figured I'd try this one out. It's very light weight and flexible, and it coils up out of the way without feeling like it'll yank the airbrush out of the holder. I'm not sure if the 1/4 inch fitting is NPT, NPS, or BPS. I tried a few different 1/4 inch I/M plugs to connect it to my standard shop compressor, and the ones that threaded on the best for me had a shorter threaded section, so you may need to try a few to get the most thread support if you are going the quick connect route. The 1/8" end was fine and mated well with the Grex GMAC .
