Air hose connections question.

[demarpaint]

TIA Due to issues with my hands I am finding it a PITA to connect and disconnect air tools from hoses. I currently have Milton V plugs and connectors, and often find myself battling to switch tools. I did some searching and stumbled upon Prevost Air Couplers ERC071201, and want to be sure it will work with the Milton V fittings? Any recommendations are welcome. Thanks!

When I switched to PREVOST I purchased both couplers and plugs so can't help you with your cross match but the plugs are inexpensive if you want to go that route.

 

[demarpaint]

Thanks for the reply. I have quite a few plugs to change out, hopefully someone here has a definitive answer. I'm not opposed to changing them, but if I can save a few $$ and the time changing them I'd prefer to go that route.

You should look into the CEJN eSafe couplers.

Hook the tool to them and put a drop of oil at the joint, twist it around d a turn. Put right at the plug coupler connection.

Thanks. I had done that before and it didn't help much.

Some styles it might not, I havnt used them all but with the ball style it does a lot.

Not surprised.
This coupler is inherently hard to connect. The only thing that might help would be to lubricate the large internal o-ring with teflon.

 

[Stedlin]

The V coupler uses a large pressure and spring loaded o-ring. The absolute minimum force required to connect a plug would be .2 times the air pressure + about 5 pounds for the spring. Friction of this o-ring can be quite high as it has to slide under full line pressure.

A good friend just told me which Prevost connector will work with the Milton V fittings I have. It's the PRVESI071201S, which is what he is using with the same plugs I have. He said it will be a little easier than the Milton connector I am currently using, so I ordered one to try. Worst case is I'm out a few $$. Thanks for all the replies.

Great to see you have a lead, keep us posted

Sounds like you found an answer to this question! If you need further help, feel free to reach out to me, I work for Prevost and can help with part numbers.

When I was struggling with couplers because of hand problems, I went with Stedlin and it solved my issues. I have affiliation, just a satisfied customer.

Prevost color codes their quick disconnects (the button color).

Green = European high flow (Milton V is interchangable with this)
Blue = Industrial standard
Red = Automotive fittings/Truflate (T code)

All details available here:

I would just recommend buying a bag of fittings to go with whatever standard and size (1/4 vs 3/8) you desire to run.

I'm currently running the green euro standard with all Prevost hardware. Disconnecting is as simple as pressing a button, little noise, nothing flying off.

Putting the fitting back in is still a challenge however as you're trying to overcome the air pressure in the line.

It may be worthwhile making a fixture to hold the quick connect to give you the ability to use both hands for leverage.

 

[Stedlin]

The number one reason I decided to design air tool couplers was because I found them all too difficult to connect.

I have a compressor and a hose reel on order and I'm preparing to outfit those and my air tools with matching fittings so I'm interested how this works out for you.

I've looked at Stedlin's stuff and it all looks nice as well though I thought I saw somewhere he recommended the Prevost Safety Coupler for attaching to the tank. I think the "Quietplugs" should help minimize the noise and flying hose issue but I don't know if they're any easier to connect/disconnect. Mr. Stedlin, if you're still following, are the Quiet plus more restrictive than the "Full Flow" plugs? If so, at what pressures/flow rates does it really start to matter?

The Stedlin QuietPlugs have a 5.5 millimeter bore and the Full FLow plug has a 6.15 millimeter bore. The couplers I designed require very little force to connect. That was very important and the main reason I decided to not make them compatible with the Euro high flow plugs.
The flow rate differences between the QuietPlugs and the Full FLow only starts to be of significance at flow rates over 30 CFM.

 

[sberry]

Yes, 30 would be a great benchmark, the hi power 1/2 gun is probably in the 25 range. It can survive some loss. I am not sure I still grasp all this,, the Stedlin is a coupler designed to work with these other plugs?

Here is something to consider. We fuss with the loss then add extra, what is the connection at tank or hydrant? There really shouldn't be any? We have a couple exceptions it they are irrelevant but basically 1 coupler in the she system, at the tool. The rest all screwed. When I started out had some hydrants and disconnected charged hose but never do now, hydrant is useless without a hose, I screw the whip or reel whip on.
Don't got to worry about another fitting, loss or leak.

 

[sberry]

Pic 1 is the right way, all screwed to the reel. Pic 2 was old and still that way, some of the rest of it has been changed. It was the first air drop and we did break the rule and do have an extra connector, they are hi flow, must not of had a swivel handy when it was plumbed. I think pic 3 may be the same way in the paint bay, a connector as a disconnect to the reel.
Pic 4, disconnect valve screwed to the main, all rubber and equipment after. Goes to that stuff in pic 3.
Pic 5 and 6, valve ahead of fil/reg, reel and whip screwed, couple on end of whip and reel. Note in 6, valve ahead of union. Same in pic 1, valve on main pipe, unions, 90, regs all follow.

 

[sberry]

This is a station, filter around the corner, the pre reg connector could go, its never used but reel and plasma on this circuit, plasmahas occasional leak i havnt fixed, i add a valve. I got an outdoor feed i use about once a year, i didnt even plumb it on, simply feed it from the reel.
I know why we left the coupler to the reel. If we ever needed to could hook 1/2 hose on there.
