Sparmax coiled air hose 1/8"-1/4"

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 .

Physical observations: two piece compression ferrule on both ends. The coiled tubing I believe to be HDPE and resist compacting between two finger pinch nicely. The 1/4 end attaches to my FishEye Filter (available @ Spraygunner) at the compressor. The 1/8 end connects to my NoName 4-way manifold (available @Spraygunner) at my easel. The coil expands and contracts up to 6-10 feet without causing me much concern (it can expand farther, but Id suggest buy a straight hose for that.
