Dixon Valve & Coupling DCP20B Brass Air Chief Industrial Interchange Quick-Connect Air Hose Fitting, Plug, 1/4" Coupling x 1/4" NPT Female

Nice Brass fitting, works as intended.

This is a solid brass fitting. I put it through a torture test asI have never used this brand before. I tried bending/crushing the coupling and then dragging it along the floor. It did well with the torture test and I am will to order more. When hooking up to your air hose be sure to use the teflon tape. Fits my quick release and had no air leaks. There is no reason to spend a lot on these couplings this brand will perform very well.

I bought one of these and some other brands of quick connectors for my air compressor. This coupling is the only one that works well. It feels like quality construction, most importantly on the threads. You can hand tighten these and the threads still won't leak air. Do yourself a favor (and save yourself time and hassle), and spend a little bit more to get something that really works well. You want quality items when safety is involved.

I work in a humid workshop and if I use steel connectors they will corrode and the corrosion will flake off and inter my air tools. If you can afford it I recommend replacing all of your steel connectors with brass, just look inside the fitting and you will see why.

got this with a plug to keep in my compressor. will keep all dirt and crap out when not in use

Dixon and Amflo both make high quality plugs and couplers and we use a lot of the Dixon DCB 20 couplers with the reverse action collar. Bought 3 of these thinking they were made by Dixon. I immediately noticed that the brass was very light color and extremely light weight compared to other fittings, and there was no Dixon name stamped on the plugs. Then discovered they won't snap in the corresponding DCB 20 coupler. Your might get some real ones or you might get the cheap crap that I got. They do seem to work in the Amflo C20 coupler but the questionable metallurgy might make them unsuitable for safe operation. I'm past the return date when I installed so guess they will go in the metal recycle bin.

Coupling works as expected

Absolutely some of the best connectors EVER! Work well, with no leaks. Of course, when you are dealing with metal to metal connections, you need to use some silicone tape, but that's to be expected. Use can couple of wraps and no problems! Highly recommended.
