Milton V Couplers

[asallwey]

Anybody use the high flo Milton V couplers? If yes, do you have them on all your lines? Considering a couple for an impact gun line.

 

[Hilltopmasonry]

I have them and like them, when you compare the sizes to the El cheapo ones they are noticeably larger

I only have a handful of air tools so I put them on all of them

I use them on all my airtools...

EDIT - I use H size

I have a mix of V couplers and M couplers. I put a female V coupler on my compressor and also on the hose that connects to it. The male M couplers work with the female V, but leak a little. My compressor has a lot of SCFM, so other than the hissing noise, this is not a problem. I got the V couplers mainly for my HVLP spray guns.

 

[asallwey]

Thanks for the feedback guys. I think I'll try a few. I had heard they were compatible with another style, but forgot which one. Thanks for the reminder Joe.

I wish I could find some in V-style in 3/8.

Threw mine away, they leaked like a sieve, not right away, but 2-3 months later

I have the 1/4" V style on everything. It really made a difference when using my air impact. It was not able to take some lug nuts off of a big truck I had with the standard 1/4" couplings, but once I switched to Milton V styles, it was able to.


I have an IR 2235 Max impact. It's no slouch. The extra airflow really made a difference in it, still.


To be fair, both of my air compressors I put a T on so there's one Milton V female coupler and one standard 1/4" coupler at the compressor. I also made two adapters in case I loan one of my tools to a friend with a V ****** on it or borrow a tool with a standard 1/4" ****** on it. One adapter is a standard ****** paired to a V coupler and the other is a V ****** paired to a standard coupler.

I did more looking after reading your posts. There was a good thread here on GF about these couplers in 2017 (https://www.garagejournal.com/forum/showthread.php?t=348896) that had some interesting comments. Most of them were positive, some mentioned leaking, and some mentioned that the Wilton plugs were the best buy but to buy the more expensive couplers. One also mentioned that they were not rated for impact gun use.

I couldn't find any info on Wilton (https://www.miltonindustries.com/couplers-and-plugs.html) to support the no impact gun use. Nor did I see any suggestion to use a whip hose as some have suggested. I may have missed it, so would be interested if anyone has facts to support either position.

Then just for information, I pulled the following from Wilton.

1/4" FNPT HIGHFLOWPRO® V-Style couplers will accept A, M and V-Style plugs, however, to retain maximum air flow use V-Style plugs. V-Style couplers have a 1/4" basic flow size and a maximum pressure of 300 PSI. Air flow rated at 74 SCFM.

And since I use the A style plugs:
1/4" MNPT A style plugs are case hardened steel and plated to resist rust. A style plugs have a maximum pressure of 300 PSI. Air flow rated at 34 SCFM.

There sure is a difference in airflow!!! I think I'll look into adding a few of these for selective tools and line.

PS How do I post a url under word, like the Wilton url under the word Wilton?

 

[99LeCouch]

Have them on my air tools. I did the whole system in those couplers. It made a noticeable difference for my impact.

No leaks at the couplers with the v style. Using a smaller one in a v style quick release will hiss a little. Not a big deal for me.

How?

I've been on V fittings for easily 6 or 7 years now with the original couplers and don't ever leak with V fittings. A couple of my tools on M that I never switched out will sometimes leak in the V coupler if I put a lot of strain on the fitting, but hardly worth mentioning.

 

[asallwey]

I've always used the steel plugs. Has anybody used the brass ones? Do they hold up? Seems the price is better.

 

[goodwrench]

i have had a lot of problems with the v couplers too. I have two right now that the o ring that seals it off when you unplug a tool, has become dislodged and won’t seal. I’ve replaced three or four more for the same issue. the concept is great and the extra flow is nice, but i’m my opinion the couplers just do not hold up even for light use that mine have seen. i wish i had never started buying them. i have half the v and half m’s. it is frustrating trying to remember what fits what. and while the m’s fit the v’s its a sloppy fit. the v are a copy of a coupler that i can’t remember from where over seas, that i think was originally used for high volume low pressure paint guns. i have wanted to see if the original expensive version of these was any better quality. i’m not sure the slight increase in air flow is worth the switch. m’s have been used for a long time for air tools in shops. if you really need more air flow than the standard 1/4” m on a 3/8 hose, it’s probably time for some 3/8 body size plugs and couplers and some 1/2 hose. you lose the most pressure from undersized regulators and 3/8 hose. i run straight off the tank on single stage compressors.

 

[sweetk30]

i started out with devilbis hvlp gun spec units then noticed there the same as lots of other high flows . i needed some more so i got a pack of assortment in the flexzilla brand and they all work together just fine and been doing so for a few years now .

 

[MattT]

One also mentioned that they were not rated for impact gun use.

I don't think any QCs are rated for high vibration applications like air hammers & impacts. So you're supposed to use a whip but very few people do. You're not supposed to use dynaswivels on these tools either but they make the tools much easier to handle in tight spots.............................

Also you mentioned brass plugs. You definitely don't want to use those on tools because they wear much faster than steel.

the v are a copy of a coupler that i can’t remember from where over seas, that i think was originally used for high volume low pressure paint guns. i have wanted to see if the original expensive version of these was any better quality.

Milton V are "European High Flow". Better quality ones are available from Parker and a number of european companies.

 

[04chase]

been using these for a few years on everything . my shop , my service trucks etc
i keep an extra prevost female on board my truck as ive lost a couple to heavy use and dirt . they wont release or continue to leak air without releasing. out of about 20 of the prevost ones i have on multiple reels , whips ive had only those fail. i will mention all of the female couplers are made by PREVOST (the black with green button ). i prefer these to the standard metal sleeve type. for the plug or male end, i use all of the above . milton , prevost and flexzilla is all of my hose now.

i even use them on my 1" pneumatic gun rather than a bigger hose and connector with no failures yet. though i dont use it as much now that i have the 1" milwaukee cordless.

these are the best couplers you can use on 1/4 npt stuff in my opinion. not sure why everyone hasnt made the switch.

From constantly connecting and disconnecting air tools, some had been changed 3 or 4 times. They leaked with no tools in them or with tools connected, There are multiple threads all over the net, with people having the same issue.

I switched to Amflo T series, rated at 67 scfm vs the Milton V’s 70 scfm, to me the difference is nothing, but they so far, none of the 70+ couplings I have, have not or do not leak.

Every female end I had didn’t make it a year

 

[asallwey]

Just one final comment on this topic. I'm going to take the plunge and pick up a couple V fittings, so I started looking for good pricing. Home Depot was one of the best on Milton fittings, but the best price was JB Tools (https://www.jbtools.com/), just as they were in 2017 on the thread I posted above. After hitting their site they sent me a coupon for today, so I'm sharing it.

"Use coupon code CYBERMONDAY2019 for the 10% discount to be applied."

Funny, haven't had that problem with any of mine...and they get used pretty frequently (weekly) but definitely not in a full time shop environment.

What’s your $0.02 on coupler material?

In the past I have used brass femalel couplers with steel male fittings. A local shop near me has aluminum couplers at a reasonable price. Anyone ever try the aluminum body ones before?

Also, looking to switch out my 3/4 impacts with these fittings so I can standardize my air lines instead of having a mix of 1/4 and 3/8 industrial fittings. Should I put a small section of hose on the impact to keep the hammering action on the fitting down? My pin clutch is really smooth, but the twin hammer really rattles.

I bought the Milton V colored couplers to change my whole shop over to the new style for a more affordable price. They are all aluminum. I would not recommend them. Not made in the USA and I have gone through quite a few already. This was in my thought process as I figured once they wear out I will swap with the made in the US couplers.

The male ends were a good fit and finish but even after only a few uses you can see deep marring marks where the ball bearings lock it in. The females have been decent for usability and seem to hold up well from appearence but also start to leak after what I consider a small amount of use. I have replaced about a dozen of each in less then a years use. (not a professional shop but heavily used DIY)

All in all I am not dissapointed in my decision as I did get them for super cheap and they are still better then some of the cheap offerings from big box stores, HF etc. I couldnt afford to swap to all USA made at the time and it was much easier just doing it all at once instead of having to use adapters. That being said buy once cry once. Plenty of my lesser used tools still have the aluminum on there but I replace about one or 2 a month with the better quality.

 

[vanapplebomb]

Thanks for the review. Sounds like I will be sticking with steel couplers. With aluminum being such a soft material, I’m not surprised they get beat up fast, particularly the male ends.

 

[kythri]

***** to hear the aluminum ones aren't up to snuff. I was looking at getting those purple ones.

All of my V stuff to date has been brass. Haven't had any issues with it, but was going to be in the market for some new plugs and couplers. The Milton ColorFit packs were pretty reasonably priced.

Ah, well. Brass ones have been great, I'll just buy some more brass ones.

From the back of the retail package of two Milton S760-1 V style steel coupler plugs, I will quote the information I offered in that 2017 thread:

"Designed for HVLP (High Volume Low Pressure) applications. When used with impact tools, a snubber hose is required between tool and swivel."

In other words; if a coupler plug is threaded directly into an impact tool, the coupler will be prone to excessive vibration and shaking.

Many users do not like snubber, whip, or "leader" hoses on their impact tools, as they are more coblesome to store. However, I favor the use of these hoses and the type V couplers. For Me; the extra coblesome hoses do not pose an issue.

 

[vanapplebomb]

I just switched everything over from industrial and aero 1/4” to the high flow plugs. Low consumption tools obviously didn’t change much, but man is it night and day with big air users like my drills. My half inch drill in particular...and I thought that was a nice drill to begin with. Now it is like a whole different tool. Awesome.

Running 120 line pressure to get about 90 at the tools.

For now I have fittings directly on my tools. The ratchets, die grinders, and 1/2” compact impact have 360 degree swivels, so I feel ok about that. I do not have swivels on my full size 1/2 impact, 3/4 impacts, and air hammer because I don’t want the added flow restriction. Because of the vibration, they really should get whip hoses instead of plugging right in. For now I will see how well things hold up to heavy vibration with air couplers directly threaded into those tools.

 

[kythri]

I've been using brass Milton V stuff for a few years now, no issues, no leaks.

Had a mish-mash of M-style/Industrial stuff for some time, and it was all leaky. Converted over to Milton V's and solved all my leak issues, and they haven't come back.

No issues with any impact tools that I've run into.

 

[dnschmidt]

The so-called Milton V are just the normal European style couplers. Milton surely didn't come up with them first. The best of these are Prevost. Use the cheap Milton plugs and the Prevost couplers and you'll be golden.

 

[demarpaint]

They're on all my air tools.

 

[sberry]

I use H, got a big box of couplers at a sale and bought s few more here and there, last time scored 5 at a flea for 5 a piece. They are 72 rated and I use them on my 3/4 gun and 1/2 hose. I have 1/2 on my truck and 3/8 everywhere else, I can tap it but simply so rarely use it that its almost irrelevant. I got all the reels screwed, all the whips screwed on the incoming that basically there is only 1 coupling in the system. I got a couple places violate it but with the big fittings doesn't really matter.
I connect at the tool, its really for disconnecting.

 

[bastage]

I just had a bunch of these delivered Saturday. Bought 2 boxes of the plugs (MNPT & FNPT) to switch all my tools over & a couple couplers (one for the end of my reel & one for my little spring hose). So far these are very cool. Lots off airflow, but I have only tested with air guns so far. Noticeably more air then the old M fittings.

 

[infinkc]

Question, not sure if anyone knows. Milton make a 5-1 coupler that can accept the V connector. Was wondering does it flow the same as the V couplers, or does it just work with the V.

Thinking of using all V at my new shop, but would be nice to use my existing fittings still for some tools.

 

[PhantomEB]

They on all mine and when I do the wall manifold system down two walls I probably will continue using them....time to go see what amazon has them in bulk for.

 

[zmotorsports]

I had a few on certain hoses and tools in my last shop. Mainly the larger 1/2" guns and blast cabinet but when I set up my new shop a few years ago I converted all hoses and all air tools over to the Milton V-series and haven't had any issues with the couplers thus far.

 

[NFH2740]

All my air tools have V fittngs. I prefer Prevost couplers as I find the Milton is hard to release or connect with just one hand.

As stated, avoid the aluminum fittings.

The hi flows are better, seems someone had posted losses thru these fittings at rated and we see the A style rated at 34,,, but what's the real loss at 25? What is the loss of the 74 fitting at 25?

 

[chicken12]

I use the Prevost high flow high flow couplers for the last 2-3 years and they have been great. Have you looked at them?

I have been reading and watching videos about the PREVOST brand and I am very impressed. I found out the company is French and the st in the end is silent
