Airbrush Quick Release Disconnect Coupler with Adjustable Control Valve Fitting Adapter with 1/8 Inches 5 Male and 1 Female Connections…

Increases working time. No air leaks.

Easy to use

These are very handy for quick changes and multiple lines but I find that the adjustment dial is prone to failure. I had to send one back for replacement and a second one is now starting to fail.

Good deal and a nice addition to my airbrush. Work well. They do leak a little more than a fixed connection (my tankless compressor comes on every 15 minutes as opposed to every12 hours or so), but this doesn't affect their usability.

This is a very handy hose fitting, it allows me to quickly change between airbrushes without having to clean one color out of the brush to use another. I like the air regulator valve to easily change the air pressure without having to touch my compressor.

Horrible quality control and I would recommend you do not buy these. Of the five stems, only two work without leaking. The standard diameter for the quick disconnects should be ~.195", three of the stems that came with the kit were below .190". That might not seem like a lot, but for an air fitting it is the difference between a functioning part and something that leaks so bad your compressor needs to run constantly.

So like the picture the coupler came connected to one of the connectors while three were loose in the bag. Those three had completely different type of internal washers the outer knurling was rougher and wider spaced. It's like a secondhand molding never as good as original. That said they barely fit within tolerance to fit the coupler at all. So quality on 3/4 connectors is subpar. But since I bought this set only needing one connector I got what I paid for. I'd recommend a different set for the coupler or the connectors. The main connector is great and same quality as others I've bought and had in the past but the drastic quality difference from within the same purchased set is disappointing. Label the listing a mismatched bargain thrown together set and be upfront about it... Then I'll rate it 5 stars but omission is a huge negative in my book.

I liked it use it for airbrushing
