Milton V-Style or Automotive

[IT_Architect]

Milton V-Style or Automotive? They flow almost the same, 74 vs. 70. Here is what I'm looking for:
1. Easy release at high pressures.
2. Don't leak when the air tools and coupling are misaligned a little.
3. Better airflow than my type M.

Thanks!

PS: Am I wrong about automotive? Is the 70 for AMT?

I use 3/8 automotive type (Milton type G). They have a lot of meat around the locking groove. Should take a century to wear out.

>I use 3/8 automotive type (Milton type G)<
I've only used 3 different kinds, A, M, and T, and I currently have Ms and a 50' 3/8" hose with 1/4" NPT ends. I need to make a change because every time the hose is slightly misaligned with the tool it just lays there and hisses and the 1/2" impact doesn't have the power like when I used it at the dealership before changing careers. It couldn't be the compressor because it is a 6.5 HP 2-stage Ingersol, 175 PSI and 80 gallon tank. I do have a cheap HF 1/4" pressure regulator which may have something to do with it.

G-Style 3/8" is available in 1/4" NPT and 99 cfm. Then I see for the G "1/2 Basic Flow Size" and for the V "1/4 Basic Flow Size". So what does the 1/4, 3/8, and 1/2 mean? It can't be body size because the hole in the V-style is already larger than 1/4". The hole in the G can't be much bigger than the V or there wouldn't be enough metal between the hole and the threads in the 1/4" NPT. I hear the 3/8 is more difficult to release the coupler at high pressures. I need to be able to pop the tool off at high pressure, so I guess I'm best off with the V-Style?

I switched from a generic type g coupler to a milton and releasing the tool is a lot easier.

That seals the deal for me. I'm just going with the V-Style. Thanks all!

You can have all my old V plugs and couplers.

BTW what are you running you need 3/8" plugs?

 

[bsaint]

I took out the two plugs so you can see the difference. Type G is a much more heavy duty plug. Larger groove. More meat on the end. Its a lot more durable. But if you need high flow couplings for filling up air tires, type V is the way to go.

I need fittings that don't leak. I need airflow for a DA sander and 1/2" CP air wrench and sometimes an air blast for peeling paint. I run the pressures high. Since I need to make a change, I need to do my homework on couplings and plugs. Thanks tons for the pics!

PS: I'll say this, the Milton catalog is nuts. They have some part numbers with S in them and some not. Some of the Ss are brass and some steel. Some part numbers have a -1 that means two to a card, but adding the -1 also turns them from brass to steel. Often the picture shows brass but the text says steel and vice-versa. I never seen such a confused catalog in my life.

I recently went down the same isle that you are going down. I went with the V-style. My decision was based several reasons. First, the compatibility with A,T and M style. Second given a length of hose and size of hose will only flow a certain amount of air. So I sat down and figured out the size of hose that I would be using. What tools I would be using. Then went by the general guide line for air tools. This made my conclusion and went with the V-style. As far a toughness mine live on my truck so they will occasionally take a beating. So in conclusion the compatibility of the v-style and my cfm usage made me go with the v-style.
I hope this helps.

I don't see the cost of couplers and plugs as costing any more for V-Style than any other style from Milton, and replacing everything just doesn't cost that much. I just want fittings that don't leak and disconnect easily at high pressure.

For cost savings I vote HF 3/8 automotive 1/4 npt

Does Milton make any V-Style couplers in steel?

I think I remember reading in their catalog they recommend using steel plugs on impact tools. I could be wrong but I don't think they make steel Type-V couplers though.

Also, the items with a -S is for a carded package suitable for retail display.

And the 1/4,3/8,1/2 body size is not related to the threads on the plugs or couplers. Think of them as trade sizes.

I think the optimal setup for garage usage is a 1/2" hose with 3/8 fittings using Milton Type-V plugs and couplings. Most tools are 1/4npt and some are 3/8npt. Both can be outfitted with Type-V plugs.

Fun fact: Milton invented the I/M style coupler and plug.

Got it! I don't see anyone but Milton with V-Style.

I just received an email from Carlos at MiltonIndustries who doesn't seem to speak good English and in all caps he wrote:
"WE DON’T SALE ANY STEEL V-STYLE COUPLERS ."

PS: It appears that the S is suitable for display, and the -1 means steel for the plugs, and because there are no steel couplers, there are no -1 couplers. I haven't heard of Milton couplers not holding up, so I assume from that the fact that they are brass is not a disadvantage.

I haven't TRIED It out, but I am suspecting/feeling very strongly that everybody does...but its all called something else. I think the V-Style is really -Euro-Hi-Flow, in the various model types each MFG wants to call them, and interchangeability info is rare.

I'm a Parker guy, so I went with Parker RF series...haven't regretted it a bit. I don't own any Milton-V fittings so I cant test compatibility, but I'd bet they are the same.

IF anybody has any Genuine Milton fittings, try these HD fittings out...I know they interchange with my Parker fittings...Same interchange as Milton claims...the female coupler will accept I/M and Hi-Flow, the males will only go into Hi-Flow.
