14 Pieces Airbrush Adapter Set Airbrush Quick Disconnect Fittings Hose Quick Release Adapter for Air Compressor

I haven’t been airbrushing for too long, about 10 months or so. As I’m experimenting with different gear and mediums, I keep swapping between airbrushes on the fly.That got annoying fast. I have a 2-gallon air compressor, so my air supply is good but it’s still a hassle to constantly unthread and thread different airbrushes onto the hose. So, I decided to go quick-connect and bought these.Well, as mentioned in the review title, it didn’t work out well. I got six male fittings to attach to my airbrushes, and four of the fittings leaked air so badly that my compressor would constantly turn on to keep its tank filled, and again, it’s a 2-gallon tank!I contacted the seller and after sending them a photo, they sent me a replacement set. This second set was a bit better; three of the six male quick connect fittings leaked air. Between these two sets, I have enough fittings that don’t leak to cover all five of my airbrushes.Also, a note for anyone that might ask: Yes, I sealed the threads with Teflon tape prior to connecting fittings to my airbrushes and to the hose. Also, I lightly rubbed water on the fittings to test them and the water bubbled around the male quick connect fittings when they were inserted into the couplings, there was no bubbling at the threads.So, I’m a little uncertain as to how to score these. I’m glad the seller worked with me, but let’s face it, out of a group of twelve male quick connect fittings, only five of them are airtight.I can say that the female couplings in both sets are airtight as well. I’ve already attached appropriate fittings to allow my airbrush hose to connect to my air compressor, so I have not used any of the other fittings in these sets. With all of this in mind, I give this set of fittings 3.5 stars.I guess if you only have one or two airbrushes and don’t want to pay a lot, then this set might be worth consideration. But only if you are willing to test the fittings and determine which ones are good. But if you have multiple airbrushes, you’re rolling the dice by buying this set. If you do, I hope you have better luck than I did!
