ColorFit Coupler & Plug Kit (5 Piece), M-Style 1/4" NPT Red

I finally got sick of the mix & match air fittings in the shop so I checked out Garage Journal to see who made ones worth buying. When I found these kits from Milton I decided to try them out. I got them in, replaced the fittings on one air hose and a couple air tools and went back and ordered 2 more of these kits. These don't just push in, you have to pull back the collar but they fit and seal tight with no leaks. I have gone through and replaced every air fitting I have with these guys and couldn't be happier.

Nice airtight fit. No hissing. Silence is golden.The color coding makes it very clear that couplers and plugs are matched. Even in a home workshop, where everything ought to fit because you took care to buy matching fittings, it's nice because everything is clear.Sooner or later a tool will get loaned out, or someone brings a few tools by so you can work on something together. Then your planning ahead will make a difference. If air tools won't quite fit right then it's clearly not YOUR fault.

Purchased a new air hose and needed fittings. Purchased this set, taped the threads and installed the quick connect female on one end and a male connector on the other. No leaks and they perform to my expectations.

Don’t waste your money the air bung snapped in a couple of weeks and the connector leaks terribly spend your money somewhere else

Cannot use for anything that vibrates heavily, the edges burr up.

Color coding has its benefits

Makes my air tools look professional and they match my color scheme in my garage. No leaks and they do the job

Precisely machined, fit every air tool I have with no leaks and looks good to boot! Very impressed with the quality. Highly recommend!

I would prefer brass connectors these are very light and I afraid tightening them damage the threads or break the connector. So far is working well.
