Air Hose Coupler

[redmed]

Looking for a good set of air hose coupler fittings. The ones I have leak and are hard to connect. What are some good brands?

 

[Sokoloff]

I like the Prevost safety couplers a lot. (one push lets the air pressure hiss out of the downstream line and then a second push releases the coupler)

 

[koditten]

I would be all over those if I didn't have so many hoses already using quality Milton couplers. Kinda spendy. I'd have $500 involved if I switched over.

I like the Prevost safety couplers a lot. (one push lets the air pressure hiss out of the downstream line and then a second push releases the coupler)

How are they when connecting a tool while the hose is under pressure? Will the coupler work with standard male fittings or are Prevost fittings required to work with the coupler? They look interesting.

I did this search recently and came up with Milton V as one of the front runners.
So far so good, really like them. Way better than the cheap generic stuff I had.

 

[GirchyGirchy]

I like my Dixon D-Series push-to-connect, for my admittedly very low use. I think their Air Chiefs are higher flow versions maybe?

 

[toplessHO]

Ive got these because I have some many different types of hose connectors
fits 5 different styles
made in USA by coilhose
they are safety release too

 

[maxpower_hd]

This is the type they use at the shop I work at. We tried the Provost as well and they worked well. But they didn't hold up as well as these do. These are also universal so if I bring a tool from home that has a different fitting it will still work.

THIS! I switched to Milton V and I noticed the extra kick from tools. My 3/8 aircat ratchet zips the longer bolts out faster. My blow gun even seem harder to hold to when blowing out parts... Milton V! And most importantly, NO LEAKS after a year.

Also, these 90* swivels are the ****! Eric O from SMA on youtube turned me on to these.

Parker European. Get them through Zoro when on sale

 

[Sokoloff]

There are different Prevost for different profiles. I have ones that interchange with the Milton V male ends. (That's the green colored button Prevost.)

I find them OK to couple while the line is pressurized. You need to push a bit, but it's nowhere near as difficult and fiddly as the metal collared couplers I was using before.

I got a lot of stuff or I would change. It would only take a few couplers to do the majority of the work but I have a system that has been assembled over 3 decades, couple buildings and a couple trucks.

A lot of companies make decent stuff. In your area Milton should be super easy to find as they are out of Chicago. Parker is also good. Basically if you skip the $1 bin at HF you are going to see an improvement. Whether or not you go high flow Milton V style or standard I/M, you still need to be aware of your pressures and set accordingly. Remember that 90 PSI air tools are designed for 90 PSI working pressure, which means the regulator needs to be set at least 110 PSI. A gauge at the tool will tell you exactly where you need to be... The Milton V style will give less pressure drop which may be more important if you have a single stage air compressor. The other possibility is to use 3/8" I/M couplers. Home Depot sells them with 1/4" NPT threads, but if you go down to Northern Tool they won't have that, but always have the Milton V style. At some point is comes down to price/availability.

 

[bmwpowere36m3]

In our shop, we've always used 1/4" I/M type fittings by Milton or Foster... quality fittings, "standard" size (easy to find replacements) and long service-life. I picked up some v-type Miltons on sale, but I wasn't impressed with the sealing design.

When you start getting into the "high-flow", safety or European fittings they start to get pricey.

 

[southalabama]

Milton "V" for me.

why not change to the style I posted and never worry about what fits what again?

 

[jallyn]

Milton V Style for me. High flow. No leaks. Way easier to couple.

 

[zmotorsports]

Milton "V" series here.

Mike.

 

[Leveleer]

Milton V Style for me. High flow. No leaks. Way easier to couple.

I have tested several Milton V couplers and they all work about like this one in the video.
Milton V at 120 PSI

At 80 to 90 PSI or so, I find them acceptable but not much beyond that.

 

[sberry]

I am using type H,,, I don't remember one from another. Is there one fits that plug that is easier?

 

[lightning02]

i use Milton V high flow couplers and plugs as well on everything. no problems. big improvement when i swapped them.

 

[Leveleer]

I forgot to mention in my previous post about the high Milton V connecting force that during my testing, 2 Milton V's in a row failed when the valve piston jammed in the full open position when the o-ring came partially out of the groove. Not good.

Are there any other safety version air couplers that fit multiple connections like the coilhose version?

When I used to sell Parker quick connects the universals were a band aide and where known to wear our a lot quicker than the proper quick connect.

I'm not sold on using them everywhere maybe on one hose when it is used for a odd fitting seldom used.

OK I'm pretty well convinced to give a Coilhose coupler a try. While I was checking them out I see it comes as a 5 in 1 version and a 2 in 1 version. I will only need it to fit Industrial Interchange & Automotive (Tru-Flate) Interchange fittings and wondered if the 2 in 1 version would provide a better connection/seal with those two types. Has anybody compared the two versions?

 

[Bcom]

Right now im using an Amflo that seems to fit any fitting ive got in the garage. I got it at walmart for a couple bux. It really works well and dossnt leak, however i have found it hard to disconnect from my air tools. Just want something thats easy connecting and disconnecting as well as fitting multiple air fittings since i jever know what tool has what fitting on it

 

[Bcom]

I watched the coilhose video and it looks promising however i dont know if i like having to engage and disengage the black sliding part to turn the air on and off. I know that sounds trivial but just seems like a failure point to me.

I had high hopes for the Coilhose coupling. I tried using it and it developed a leak after just a few basic tests. I'll disassemble it soon and investigate.
I made this video shortly after I received it.
Coilhose and Legris initial impression

 

[Bcom]

Is there any decent safety coupler that works well then that will fit both aro and industrial fittings? I think thats the only 2 styles i got in my shop

 

[bmwpowere36m3]

******* are cheap, just replace them all to 1 style... unless you work in a shop swapping tools with others.

This is the answer

[redmed]

I ran across this video explaining air coupler differences and markings

Helped me understand what I have and what I want.

 

[bmwpowere36m3]

What do you have? Ones that leak... according to your first post. Its like asking what car do you want....

Do you want to replace all couplers and *******? Are you a home-gamer or pro? What size fittings (probably 1/4")? Besides no leaking, is their anything you want in the fittings? How much you want to spend, how many you need, etc...

You can go to HD, Lowes or HF... pick some up and they'll likely work fine for a period of time depending on usage.

Like I said in a earlier post I'm pretty well set on trying Coilhose couplers. Probably 5-1 unless someone tells me the Coilhose 2-1 would work with my Industrial Interchange stuff better. I spent some time on Youtube looking at the stuff suggested here and it looks like Coilhose is the closest to what I want. I like that I can shut off the air pressure at the coupler just by sliding the sleeve shut. I have spent quite some time and effort sealing leaks to my hose fittings because I don't like turning the pressure knobs off all the time. I wore out the threads on the pressure knobs of my old compressor and installed a shutoff valve just before the hose to stop leaks but still have a slow leak in the hose coupler that drops a few lbs of pressure every night. I also like the ease of plugging into the coupler with the air pressure shut off with the sleeve on the coupler. With the suggestions here and some time on Youtube I think I have a better handle on what will work for me without having to buy a few different couplers. I think I've narrowed it down to Coilhose. I'll have to try it myself and really find out.

There have been a bunch of these safety coupler discussions as of late and I have been following closely as I have a similar concern/problem about coupling under full pressure. I was interested in the Coilhose 5 in 1 safety coupler too but I did find one "issue" that no one else has mentioned. Their 5 in 1 coupler can fit multiple styles including the high flow versions (Coilhose calls them megaflow). BUT, I noticed in the specs listed in Amazon, the reported flow through the coupler is similar to non high flow couplers. I can't find a flow spec in Coilhose's literature. So seemingly although the 5 in 1 can connect to the high flow plugs, you apparently don't get the same high flow through the coupler. Doesn't mean the coupler is ****, just that if you want to run all high flow stuff, this coupler would be the bottleneck. Can anyone else confirm I am reading this right?

I measured the pressure drop across the Coilhose 5 in 1 as 5 PSI @ 90PSI outlet pressure using a Milton V high flow plug. The same plug in a Milton V measured 0 PSI @90PSI outlet.
These tests were done at a flow rate of around 30 CFM.
The Coilhose coupler developed an internal leak after a few tests and can't be stopped.

 

[gsmith22]

Thanks. that seemingly confirms that coilhose's 5 in 1 safety coupler is not a high flow version even though it can physically connect to the high flow couplers.

Correction. I looked at ours last night and it is actually the Coilhose one that ******* posted.

If you have high flow devices run a higher flow coupler.

This does not mean using a coupler marketed as a "high flow" coupler in a 1/4" body, this means running a 3/8 or 1/2 bodied coupler along with 3/8" or 1/2" hoses.

That's depressing. It seems all of the coupler brands are **** or have a short life.
