Easy to apply and remove
Works great for an air supply quick connect. The brass color looks great and the quality seems to be excellent after a few uses. Perfect fit with my supply line and was a low cost replacement.

Great Couplers that Don’t leak
I needed two new couplers to replace some I had that were over 30 years old and they were leaking air so my compressor was constantly cycling on and off to keep the pressure in the tank up. I was replacing the air hose and got the new couplers so I could replace both at the same time and everything worked great together and now my compressor holds air pressure with no leaks, so it runs a lot less. The Milton couplers came in a set of four which cost less than buying them separately and since I didn’t need four I have spare couplers available if I need one in the future.I highly recommend this Milton Brand Coupler because they are made of heavy duty quality components and will last many years.

WOW No Air Leak!!!
Dear lord why didn’t I discover this brand quality before?!! I have been using an air compressor to blow air out for my job and the hose that I purchased came with a coupler included but that coupler is pure junk because it would constantly leak. It was soooooooo annoying and frustrating.I am not an expert at this sort of stuff so I assume all air hose couplers leaked air but man was I completely wrong because this coupler does NOT leak at all. I could not believe it. I’m so happy. Excellent product and will continue buying this brand 👌

Doesn't fit on harbor freight hose but made it work.
Didn't fit my harbor freight hose. Must be a different thread pattern. So I took the guts out and replaced those. It worked to stop the air leak. So far so good. They have a good reputation of being the best.

Buy this brand, not the cheap ones
Good quality, doesn't leak air. I thought my air compressor was going out, but it was just the cheapo couplers from HF that was the problem.

Quality Machining Means Easy Fit and No Hissing
Milton is the "gold standard" of air fittings in my 60+ years of using air for so many tools. It connects and disconnects without hissing all the time, like the leaky cheapies do. Very good quality and tolerances, make it easy to use, so I put male ends on the tools and female end on the hose and go to work.
