I'm redoing some of the air plumbing in my garage and at the hardware store I noticed there are several different styles of air fittings. When I did my lines originally the store I went to only had one style, so that's what I got which ended up being "M" style, which I'm pretty sure is most common as I see that style regularly in other buildings. But there's a T, V, ARO, and a couple others I believe.

Does any style offer advantages over the other? I don't do anything particularly heavy duty and the fittings I have flow plenty of air for what I use it for.

But it does annoy me that the quick connect fittings I have aren't as reliable as I'd like. They seem to work okay for a few months but I notice that eventually they begin to leak if there's slight pressure on them or the hose twists. Replacing the quick connect coupler always fixes the problem but this is a headache I'd like to avoid. Curious if one of the other styles might be more resistant to this type of wear, or have a more secure connection that might be longer lasting.

Any info on the strenghts / weakness of the different styles would be helpful, or are they all created equal?

The Milton high flow "V" types have noticeably more air flow:

They hold up very well + you can insert a tool just by pushing, no need to withdraw the collar.

I thought the common types were just called "industrial", "automotive", and some other type (without Googling, the name escapes me at the moment). Problem is, they're partly interchangeable although they don't fit or connect 100% perfect. It could have been the coupling I was using that was the problem too as I'm sure they're for specific types too. If I recall what happened, I had bought the various fittings in a set so obviously they matched. Later, I had to replace a single fitting and ended up buying the wrong type (not even realizing there was a difference).

I Googled this stuff at the time and don't recall that one is "better" than the other. They're just different.

I'm an industrial supplier to some major trucking companies, Milton style fittings is so far the most popular with all of my customers. I have one account that absolutely DOES NOT like quick disconnects.

As far as weaknesses, I have not had any complaints. The only part that I've seen wear out more than anything is the male quick connect fitting, it gets worn out from repeated disconnects.

Milton "M" style are the longest lived, If you don't need high flow, That's what I would recommend. The Milton "V" style is pretty good but not as long lived. I've used "M" style on my Trans benches for over 25 years with great results. The only tool I use that really requires "V" style fitting is a Proto 3/4" Impact & don't use it all that often.

The one on the right is the 1/4'' ARO fitting which 99% of NZ shops use....except where I work, where we used the 3/8'' ARO.

I've been converting all my fittings to the high flow style. There is a real difference in performance and speed.

I’m using the Milton V style/ high flow. I think a box was 10 was around $12 on eBay. The quick release fitting was just under $10.

Somewhat annoying to have unique fittings to everyone else. I’ve had to swap fittings a few times so far. I need to especially make a normal to high flow adapter with 3’ or so of hose and vice versa.

I have my air system broken down into multiple parts, one uses M fittings 3/8 hose with filters and oiler for tools. The other is V, 3/8 hose all sorts of filters and cooler but no oiler for spraying, tire filling, blow gun use. There is also 1/2 line from both oil and clean sides for higher cfm 1/2 hose.
