Milton Industries HI-Flo V-Style 'A,M,V' 1/4" MNPT Brass Body

Worked perfectly definitely will buy from them again.

I bought this because the ones I had were leaking. This fixed that

These fittings snap together fast and nicely, seem to offer a lot of flow! I disconnected mine at about 90psi and it nearly blew my ears off! Also shoots the adapter and hose off when disconnecting at 90+ psi. I will drop my pressure when disconnecting/connecting and all is great!

In my opinion, Milton quick-connect couplers have always been among the best, so I am not surprised that this one lives up to that expectation. My only comment would be that, like all high-flow couplers that I have had experience with, this one requires more insertion force than a standard coupler. If you happen to be using it at 175 PSI, it takes considerable strength to connect it. It's not the connector's fault…it's just physics. Even so, it was inconvenient enough that I fell back to standard Milton couplers for my high-pressure lines, saving the Hi-Flo ones for lower-pressure applications, such as my HVLP spray gun.

I changed all my fitting to the European high flow spec couplers. I use Milton and CEJN couplers. High quality no leaks.

This is the best air fitting out there. Size of a 1/4" fitting but flows like a 3/8" fitting.

They are what they are supposed to be. Seem to be built nicely and are much easier to use.

I got a new compressor, and plumbed the whole shop with copper pipe. I wanted a good set of couplers to get the most out of the setup. I think the V style hi flow is the way to go. Haven't used them extensively yet, so can't speak to their effectiveness running high demand tools, but I expect they will do very well. They engage and disengage silky smooth.

This is an awesome coupler. The quick connect/disconnect is just what the doctor ordered. The problem that I'm having is that the tool connect end leaks a little bit if the tool isn't held straight. There is too much movement in the coupler and thus it leaks a little bit when held at the wrong angle. Fine if I hold it in a straight line with the tool and the hose. I'm going to try a couple new male inlets to my tools and see if this coupler still leaks, but I get the feeling that it will. It's almost as if the couplers inner seal is too small. I do love this coupler besides the small leak.

Total junk. All purchased leak air around the sleeve brand new out of the package. Emailed and left several messages with Milton Industries, NO response at all, been over a week now.
