Tru-Flate couplings do not leak for me.
Harbor Freight couplings are almost sure to leak. The male plugs seem to seal well with any quality brand.
These are standard "automotive" style couplings.

Milton M-style although the forum has its V-style converts.

I am a happy v style convert.
Prevost for me. Milton worked great as far as not leaking, but I like the double click to release - first click removes the pressure but captures the coupling, 2nd releases the coupling.
If you wrench for a living that will probably be annoying, but for a hobby this works great for me.

Prevost. However, very few will pay the premium.
When I worked for Land Rover Portland, they only had Prevost couplers. The techs loved them as they were fast to couple and safe to uncouple.
I have one or two customers who use them and a bunch of the fittings on the truck that will probably never sell.

Parker Haffinin. Their high flow are also called European-style or RF Series. Made in the USA as well.

A couple years ago I upgraded all my 1/4" stuff to 3/8" body automotive style couplers and plugs. I bought everything from Grainger because they were having close out sales and some of the coupler plugs were as cheap as .19 cents each. I ended up with a mish mosh of Speedaire, Legacy, and Parker. To be perfectly honest they all work just the same. No leaks, no coupling issues, and they all look pretty. I will say the Parker quick change coupler body is easier to use and a bit beefier than the Legacy quick change coupler body.
They still have some on clearance. Here's an example of how cheap these are on closeout at Grainger. Instead of shipping I went and picked them up. https://www.grainger.com/product/LEGACY-Steel-Automotive-Quick-Coupler-1HPL7?functionCode=P2IDP2PCP

Milton might be alright compared to some other cheaper stuff, but they're absolute junk compared to Topring.

I may have to check out those SS couplers. They look pretty nice.
I have Milton V female couplers. They seem to work fine. The high flow does make a difference. I also like that they will still accept an M style or non-high flow connector.
The male ends are a mix of Milton V and HF.
A couple local tire shops use couplers with a blue plastic jacket. I swore they were Kobalt, but I haven't been able to find them at Lowes.

Around the North East Milton seems to be the defacto standard in auto shops. I have stuck with them just because they are the the most common around here and I do not want to change all my tools and lines over. The last place I worked used Lincoln style couplers, I stuck with the milton and made an adapter hose for when I had to work out of my bay. I never could see the point of the Lincoln fitting it is obnoxiously long, especially on a 1/4 drive air ratchet. Milton, best? Probably not just the most convenient in my area.

I have Milton and Prevost. I use the prevost pushbutton on hoses. The collar type can get disconnected when you drag the hose around. I use milton in the shop where they are fixed to the wall.
I use single push to release connectors. The double push style might be nice for hoses so you don't have the male end whipping around spewing air. I just don't have any of the double push style.
Both Prevost and Milton make push button connectors in both single push, and double push styles.
I've tried some of the no-name made in china ones. I won't do that again.

Milton V series for me. I had the M series but changed to the V series when it came out for the extra flow rate. Northern tool carries them and they are easy to find. If Parker or one of the other companies were carried around here I might have went with them.
I have not had one issue with the Miltons. It really comes down to what is easiest to get for you. Also if you borrow a friends or some one borrows one of your tools will they be able to connect to the tool. I for one do not have that problem though!

Prevost high flow air couplers by far the best. i have used them all and recently converted . Plus they were green and black to match my tools even better. but they are awesome and can be found for decent prices online. they do last nearly forever. I have one on my service truck that has been beat for 250k miles and it still kicking ***.

You will not regret it. Been flawless for me. Driven over them a few times, no issue.

I have success with everything except the buckets at Harbor Freight or the other dirt cheap stuff. Milton, Parker, NAPA are all fine. If you want to get "fancy" then the Prevost look nice but I haven't used them. Kind of hard to stomach the prices on the Prevost when you can get quality for far less. If the Prevost sounds like it'd be an advantage then go for it...
same ones i have but they now have the high flow versions that use the same npt threads with a 3/8 body.

Husky has a safety coupler knockoff for less than $5/ea.
I'm just sayin' you can replace them 3X for what the cost of a single Prevost coupler..

Do you use plumber's tape? I use that and it doesn't leak for me.

FYI, you brought back a pretty old thread.
But yes, I use and like those:

They're aluminum, so they are pretty light weight. And the rubber cover makes it less likely to ding something painted it may run into.
That only helps with fittings to hose/tools...the problem is generally the coupler itself.Do you use plumber's tape? I use that and it doesn't leak for me.
I am in the Milton V camp as well, no real issues with them.
I think what people fail to realize is that these things need replacing every now and then, the couplers have some rubber seals that eventually wear out. Also not dragging the tool around by the hose or putting a lot of pressure on the coupling will help keep leaks at bay. Swivel fittings or short whips can really make a difference.

Just changed all mine to Milton V's. Noticed a difference for sure.
Can the prevost coupler be used with milton V plugs?

I bought a batch of about 30 V styles for a professional shop and after 1 month the first one went and then on 8 or 10 of them the O ring came loose and jammed the whole unit up so it leaked air full blast whenever anything was unplugged from it. Happened over the course of two more months.
Scrapped all of them in favor of Dixon’s and Milton M styles before the rest could malfunction too. Never hear a bad word about the V styles but I had a real bad experience with them myself.

I have tried a couple different kinds of couplers and have had no luck with them not leaking. Anybody have any suggestions on a brand that has a good fit and no leak?

it's silly to have 10-15 threads that cover the same information.
since it's still pertinent, I thought I might update it with a potentially "new" product (not sure when the husky couplings came out)..
