Milton high flow comparison

[silagehauler]

Thought this was interesting today. Was taking a wheel off of a combine. Was using my 2135. Had been using a standard quick coupler to hook up to shop air. Struggled to take the first 3 bolts out.

This was an opportunity I had been looking for.

Swapped coupler for a milton high flow so I could use my portable compressor. My compressor does run a few more PSI than the shop, but was also using 3 times as much hose. Proceeded to take the remaining bolts out quite easily.

So, high flow couplers DO make a difference.

Once you go European Interchange (High Flow), you'll never go back.

Been running Dynabrade/CEJN 320 series for years and would never use anything else.

~75 cfm flow, the coupler stays open when you eject, they NEVER leak.

Not really a valid comparison. PSI changes the hitting force of the impact gun exponentially.

It might have had an effect, might not have, really no way to know unless you did an apples to apples.

Just sayin'.

I've finally got enough of the Milton that every compressor outlet, hose, tool, air chuck, blow gun finally matches and now you're telling me they're obsolete?

Yes, I'd love to change over to all high flow couplers, but that many new male and QD connectors, plus new hose would add up. Since I don't pull that many wheels off combines, they just may have to wait for the next incarnation.

Just for the sake of the education, the males/females are only a buck-and-a-half each. How much are the QDs?

+1. A change in air supply will make a very significant difference to how the tool is going to run, which far outweighs the coupler change.

I made a big order from these guys a while ago. I ordered about 30 female couplers and they were about $13 ea depending on thread size, plus freight of course. Better than the $30 ea I had paid for Dynabrade rebranded couplers from the local parts store.

Are they the Milton V-type? I was looking into purchasing them but they're a bit pricey and I'd need to save up.

My friend switched his shop to CEJN 320, since I hang out there I switched all my stuff over as well. SHEESH, that was like $250 in a heart beat, but I've left an airline charged for a month holding pressure.

I bought from http://westsidedelivers.com/mfgr.asp?mID=65

I changed from 1/4 to 3/8 here and it made a world of difference, so high-flow should do the same, right? It really was surprising.

Good morning.

At one time , I purchased wholesale quantities direct from Milton for the purpose of resale and received catalogs and such on a regular basis.

In the last air accessories & fittings catalog they sent me , on page 36 under the heading "basic size" , it says that the 3/8" and 1/2" style fittings should not be connected or disconnected under pressure.

I'm just throwing this out here for the sake of discussion.

 

[silagehauler]

Yes, I was using Milton V style couplers.

I realize that changing air supply makes a difference. If anything, the shop air has a slight advantage. It flows 20 ft through 1 inch pipe and 25 ft of 3/8 hose. My portable has 100 feet of 3/8 hose. The couplers make up the difference.

The point I am trying to make though, is that proper air supply matters.

At one point after installing the 3/8 coupler/plugs I went to connect something and could not get it to go because of all the air rushing out of the coupler. It turned out that I had the regulator wide open and reducing it back to a reasonable 90 psi was enough to where I can get things plugged in.

I've run the same tools with both regular I/M and then type V couplers. I can tell you it made a HUGE difference. After that I upgraded the crappy 1/4" fittings/3/8" hose we had hastily hacked together to get the compressor hooked up to the shop lines, and that probably made almost as much difference again. The few things I have left with I/M fittings plugged into type V couplers are a little better, but not much, than they were at the start.

I ended up getting most of my stuff from Northern. It wasn't cheap, but it wasn't THAT expensive. I think I spent $150 or so on couplers (and spares/add-ons) for the whole shop, and fittings for most of 2 peoples' tools.

Is that "leading competitor" Milton Type-V?

 

[tshetter]

Brass at the top is HF, steel on the right is Lowes, and the high flow on the left is Milton Type-V.

And also, the CEJN series 320 fittings are not 1/4 fittings, they are 5/16:

http://www.cejn.us/Products/Pneumatics/Standard-Couplings--*******/Series-320-DN-76/

Nominal flow diameter: 5/16" (7.6 mm)
Air flow @ 100 PSI: 74.3 CFM (2100 l/min)
Max. working pressure: 232 PSI (16 bar)
Min. burst pressure: 2030 PSI (140 bar)


Not that it REALLY matters, but it is a larger base size.

The Milton Type-V:

V-Style Couplers are Push-Type
- Maximum Inlet Pressure: 300 PSI
- Maximum Temperature: 250° F
-Air Flow: 74 SCFM
- Seals: Buna-N

I use big fittings because its what I started with and don't have to change out for use with larger tools and 1/2 hose. As I tailored my system actually backed out several couplers and have some more to go, I try not to use any but at the end of a fixed hose or hose reel. I never have to move a hose to a hydrant.

 

[kapster]

Maybe his test wasn't apples to apples, but i tested mine years ago when switching to milton v and it is a big difference. I also use 1/2" flexzilla hose, got it because the od is about the same size as 3/8 regular hose.

In case anyone didn't know, the milton v coupler is compatible with the std fittings. I was switching from harbor freight junk stuff, so I bought milton couplers and enough fittings for stuff that can benefit from the extra air. Slowly replacing the HF fittings with the v fittings.

One more,I believe I read this on milton website. When using an impacting tool such as impact wrench or air hammer, they recommend putting a whip hose from the tool to fitting to prevent wear on the coupler. Makes sense but I never thought about it. I'm sure that wasn't helping my HF couplers.

- Maximum Inlet Pressure: 300 PSI

And it looks like their 1/4" size is "standard flow" at 52.5cfm @ 100psi.....http://www.cejn.us/Products/Pneumatics/Standard-Couplings--*******/Series-303-DN-65/

I don't see any high flow 1/4", so that means the Milton V-type takes the cake, correct?
