Your air hose connection should not be leaking in any way. I have a Badger braided airhose which does not leak. This is when fitted to a Badger reducing adaptor at the compressor end and a Badger 200 airbrush.
If your compressor adaptor is a third party product it may be that the length of the threaded section may not be long enough to seal against the o-ring inside the hose connector. I have had this issue with the very same air hose connected to a generic Chinese-made airbrush - the standard vinyl air hose worked, however. It may be because the braided air hose has a loose nut arrangement which has to seal both the air connector and the “fixed” base of the hose itself.
Find the leak with dish soap and water. Bubbles will instantly appear where the leak is. Most likely on a fitting, realize a perfect threaded fitting will not leak. There are no perfectly cut threads so wrap the male end in Teflon pipe tape. Split it down the middle, keep it 1 1/2 threads away from the end to avoid getting tape in your system. Tighten 3 turns by hand, 3 with a wrench which should leave 2 threads exposed.
I ordered the Badger 10 ft braided hose from Hobbylinc and had the exact same problem, all brand new connectors and mine leaked at the airbrush connection end. I had also gotten a real cheap braided hose with 1/8" connection ends and it worked very well with an adapter, no leaks at all,sounds like theres a few of these leaky Badger hose about, maybe it was just a bad batch that came out.
I had the same problem. Either the threads on the outlet of the compressor, or the fitting on the hose, were not tapered. It screwed all the way on to the stop without resistance, rather than get tighter the last couple of turns. A wrap of teflon tape solved the problem fine. There’s not a lot of thread area to work with, so trim the tape cleanly. Try not to let an end stick into the air path where it might break loose later and cause havoc downstream. Doesn’t take much tape.
You think by now, considering how long this particular hose has been selling, they could have fixed this problem? It would seem its a regular problem too after doing a little bit of searching on different forums.
I learned long ago that threaded parts that hold pressure will leak. Depending on the joint, I use beeswax, pipe dope or Teflon tape to seal the threads. The only time I don’t is on garden hoses, as they use a washer to seal the joint.
So I used a cheaper hose to replace it from TPC Global, and now it works fine, so as I said fix that hose Badger, but then again its probably made in China !
Hows that saying go"If it ain’t broke don’t fix it !" Well it is broke so please fix it !
