Good article (halfway down the page) on air fittings/couplers
http://www.homemetalshopclub.org/news/aug03/aug03.html
I ended up picking these up from NAPA
How much where those from Napa?
What air couplers do you use?

not to take this thread in another direction but what size hose are you guys using? I currently have 1/2" that comes off of my 3/4 rigid black pipe. I have a long run from my compressor (75' of hose) and found that the 3/8" stuff didn't give me enough cfm for my impact gun.
Does the Milton type V (s764) attach to a 1/2" or 3/8" line? I know it says 1/4" NPT but I find pipe tap sizes confusing (well maybe not confusing I just always seem to forget actual size vs pipe tap size...
)
thoughts?

Milton type V couplers work on 3/8" hose & the male ends screw directly into air tools no adapters needed. Once you go to the type V you will find you will be able to use 3/8" hose instead of 1/2". Make sure you don't have any smaller fittings upstream that will slow airflow.

I went to the Hansen High Flow series. They're the same size as a typical #4 body coupling but flow like a#6. They definitely helped with my sanders and paint atomization. The extra volume makes a huge difference. I used to use the Milton short couplings but the fittings might have been causing a restriction.
Some of the hansen numbers are Coupler body 2-R16, plug 2-L16 w/female pipe thd, 2-L15 plug w/male pipe thread.

I had been using Milton Type M correctors for 30 years and just changed everything over to Milton Type V (you guys made me do it!! from reading a previous thread, Thanks Merk!!)
I am truly impressed with the flow improvement. Well worth the money spent.

The best pricing I could find was from Northern Tool coupled with a 10% or 15% off promotion code and stacked with a free shipping promotion code. When I did an Internet search there was one supplier that had slightly lower unit prices but much higher shipping so Northern still was the lowest overall cost. I bought all the V fittings and couplers a little over two months ago. Do a search for current Northern promotions or wait a bit for one to turn up that works, they are always running something.

I bought mine at one of the local auto parts stores that specializes in paints, probably 1/3 of the store is paint, thinner, reducer, etc. Had them order me in extra so when I buy a new air tool I'm ready to go.

Bringing this thread back up... I just installed a couple of Milton 766 V types. I have Industrial fittings on all my tools (I think). When the tool is on with no movment there's no leaking and I have good engagment. When I put any side pressure on the tool, the coupler starts leaking.
Did I mis-read the connector types? I'm looking for a universal/industrial fitting, what Milton type should I be getting?

Prevost has come up with a new high flow safety coupler that is "slick"! It is a safety type that after you hit the release button, it purges the air without hose whip and then releases, only after the air is purged. All one (one press) action.
Yea, little more expensive than you standard Milton steel sleeve coupler but it will outlast the standard 6 to 1. For a 1/4" thread female the part number is ESI071201. You can get then from Snap -On and Matco Tools also Sherwin Williams Automotive carries them.

So this new high flow female coupling device quickly releases the male coupling device after it is fully purged to avoid hose whip. Hasn't it always worked this way

Um, where is it made?
Milton has this same coupler (I have some), and HF carries this same style. I no longer have the old HF package, but the new HF ones say "China" while the Milton's are Taiwan.

They work great...as long as you work in a sterile environment. If your garage floor gets dirty, your vehicles drop dirt on them, or you use them outside, they ****.

^^^do all the Prevost have this limitation? I've been meaning to switch over to them.
Also looking at some Wurth stuff to crimp to hose to make nearly exact lengths, when necesssary.

FWIW, the Milton Type M are by far the most common. I've never had any problem with the genuine Milton. If I have a problem, it is always with the HF imitations. Agreed if there is a long run of hose, the Type M is too small for maintaining best operation.

I use the Schrader 1/2" SHD fittings because they're bullet proof and because we use them at the factory where I work so borrowing tools doesn't involve changing the fittings.
They aren't cheap but they will last a lifetime under normal use.
More info here: http://www.couplers.com/images/catalog/page10.pdf
And here's a couple of pictures...

My pop set all his stuff up in Schrader's that he got somewhere years ago, likely only available commercially, or industrial. I love his Schrader's but due to the cost and availability I began using Milton fittings years ago just as a matter of convenience, they are not nearly as nice as the Schraders, but they get no complaint from me.

HF, Milton, Prevost. Tomco, had a different style of the same thing. Those are a safety coupler, that releases the pressure before you disconnect a tool.

they **** because dirt or oil easily fouls them up? I was all ready to go with Prevost brand thinking the Swedes (or English or whoever) would make a good product for $25 per pop. Wurth can be bothered to send me a catalog, so they lose out on my fastener, air compressor and chemical buying I wanted to do with them. HD stuff *****, and I'm not so impressed with the Milton for Industrial. But I have had morons abuse it. Maybe this Schrader stuff mentioned will work. I htink McMaster-Carr might carry Schrader. I keep putting off upgrading and fixing all this stuff.

Milton Type V, and it made a noticeable difference in the performance of the air hogs, it's like a free torque boost for your impact.
They also accept the old cheap HF / Wal Mart connectors that are still on my infrequently used air tools.
Hose: As far as I know 3/8 is plenty big unless you're getting all industrious (over 30cfm) or running it a LONG way.

Both the Milton, and HF, look identical, and have four balls. I don't have any of this style Prevost to check. Sorry for the delay, LONG couple of days, and 10 pages of posts to go through (something at work got moved up 8 days).

If you are wondering what brand that is with the blue body and the red button it it the PREVOST brand, One of the best air couplers on the market.

The red button ones are truflate profile. I keep a lot of Prevost couplers in stock...see http://www.ultimategarage.com/shop/index.php?cPath=353 .
If you're just starting out, their High Flow profile would be the way to go....the high flow plugs have a higher CFM rating than the standard Industrial or Truflate profiles.

How many balls in the Prevost release mech?

For the one shown above (red button - truflate profile), I count 6. Of course, this brings up the "more balls" vs "bigger balls" debate guys have had for years.

Hi all,
A few questions. My current system is a mix of ARO (on the ends that connect to regulators) and Type M that connect to my tools.
Im not happy with the miltons as they're pretty much all leaking plus they're relatively low flow. I never seem to get good life out of them.
In 1/4" is the milton type V the best flowing coupler? Or is the TruFlate style the best? Or Prevost high flo as mentioned above? Are there any other suggestions for high flow?
What about quality? All my current couplers are milton brand, no knock offs.
Some of the comments in this thread indicate that milton has offshored some of there manufacturing? I actually had a milton 3 way coupler fall apart in my hands, has their quality slipped?
I like the push button safety couplers, are they better quality, how are they for durability? Can anybody confirm dirt issues? Ive had air hoses disconnect with some rough handling on my part, no fun!
What about the Oeitker Swing style couplers? How are they for flow and durability? Cost? At a former employer, we were going to that style, for safety issues, but i left before i could determine how they held up.I thought i heard that they were something like $40 each, but i could be mistaken.
I want to upgrade my system, but i only want to do this once so any advice would be appreciated. My final choice will be decided by quality and availability locally. One thing that would **** would be having the best possible fitting, but having to mail order or travel to pick up plugs, so id have to check on the availability of the Prevost Hi flo.

Milton M here. Question is the Type M interchangeable with the Type V???
Thinking of changing some over to Type V.

If you really need higher flow, consider upgrading to a 3/8" body size. Otherwise I'd recommend Prevost Hi-flow ...these are still being made in France. Not sure where Milton is coming from these days.
I like the Oetiker Swing couplers but they are a bit expensive and not as easy to use. Definitely the better choice in the pits where air guns are thrown about and Prevost or most typical couplers would be prone to accidental release of the tool under pressure. The Oetiker coupler requires a fair amount of mechanical intervention between pulling down on the collar and swinging the fitting to the 45 degree release position. SD

ultgar: Thanks for the reply.
Im considering this upgrade because my current system has leaks, and im not really happy with the service im getting from miltons. And i really hate air leaks in my shop
I also use a fair volumes of air between my blast cabinet and HVLP paint gun. Plus the improved flow will no doubt help performance of my air guns and air powered grinder. However cost of the upgrade will be a factor (ie: is it really worth it). Thats where the high flow comes in. I figure if im upgrading, i may as well get something that ill be happy with.
Where i live we usually pay considerably more then you guys in the states! No free shipping or aggressive online dealers here.
Upgrading to 3/8 might be cost prohibitive as all my airlines are 1/4 NPT.

type m ******* can be used in type v couplers. I only swapped my 3" cutoff tool, impacts, air nozzle over to type v *******. the air ratchets, tire chuck, alcohol sprayer, air drills, etc., are all restricted elsewhere anyway.
I'm just using the cheap Campbell Hausfield from TSC or HD.

I've used Campbell Hausfield parts for many, many years and never had one fail. Just a reminder that anything can be defective and just be careful, even with the best equipment.
I know Lowes carries different kinds of couplers now. I have o run up there today for some stuff so I'll look to see if they have any "high flow" type items.
