Air Fitting Guru's I need some HELP

[MadTinkerer]

I have tried google searching but haven't been able to come up with much. The shop that I currently work at is outfitted with Milton L air fittings. Looking on the Milton site, these fittings are a fairly low volume fitting. I want to upgrade to a high flow fitting such as the Milton V or another equivalent. The problem is that if someone needs to use my airline at my bay, they won't be able to due to the different fittings. Is there a "universal" coupler that will accept both a high flow fitting as well as the milton "L" fittings?
I guess a work around for this would be to put a milton v coupler at the end of my air line, and when I am not there or someone wants to use my line I could just plug in a milton L coupler into the V coupler.
I would also need a small airline with a milton L fitting on one end encase I ever use anyone else's air line.

I know this post may be confusing, but any help would be appreciated.
Thanks

Get the Milton V for your needs. Then just make an adapter with a male V and female L coupler threaded together and leave it by your air line. No small piece of hose needed.

theres no point in running a high flow fitting if the fitting in the tool is going to be smaller, you only have 1 restriction in the system and its about making that restriction as small as possible, changing over to the milton v type everywhere for me was costly at the end of it, but if the air is there and your not making full use of it then your just wasting energy and time, the cost of changing over the fittings paid for themselves in 1 git of a job

and yes i have a small adapter line made up however after comming away from a high flow fitting youll think your tool is bust when you go back to a 1/4 fitting from a 3/8... its mad but youll see a massive difference... lug nuts on a van (transit) i can bang off with my MG325 where as before i couldnt

The answer to your question is no. The Lincoln has a very long stem. The V coupler theoretically can (though it doesn't work very well) accept the Tru-Flate style and the Milton M but not the Lincoln.

I would figure out if it is really going to make a difference, I tink its psychological more tan anything else. But put a T and install 2.
Something else to consider here is some air hose vs fittings. Ina truly well designedair system there are no hydrants but a hose screwed to the line with a whip or a reel. The easiest way to improve is to remove it, not only does a guy have 1 but has 2 and has to remove a section of hot hose.
We only have one coupler in the system between the comp and the tool and that's at the tool. If I need to switch hois4e between 2 places I need another hose not another coupling. Taing 1 out is better than adding 2 good ones and is near free.
I know there can be argument here and there are a lot of ways it can work then there is the best way.
Is there a real performance reason to change, millions of mechanics make a living over a career with simple air fittings.

We had a situation on a big truck, first time in a couple years we had to use a shorter larger hose on a job. Yes, I could enlarge every component in the place and short every hose but in most cases with 2 stage there is enough headroom and can adjust the reg to makeup for minor losses. An air gun doesn't have to make as much as it can on every hit.

There is some benifit to improving distance and flow on single stage systems where its pretty much uphill from the start. Only when the system is full is the pressure good. With 50 ft of 3/8 hose a regulator isn't needed for a 1/2 air gun or 6 inch DA.

I was going t isolate some tests thru several fittings with this air gun. Basically though an improved fitting has SOME effect at very hi demand. Number 1 and easiest change I hose length. I/2 as long, 1/2 the loss.
Very similar in some sense to a common stick welder hooked to a 6 wire, all losses across the whip going in and where a huge amount is acceptable due to duty cycle as well as on the secondary with factory leads.
Considering the practical use there isn't much performance savings from a number 10 wire and a number 6, depending on service and length losses at normal output use are so negligible that the operator cant notice and when the machine isn't in service totally irrelevant.
The number 12 cord has a huge loss. One could change the 12 to a 10 with the same connectors at the machine end and see a big jump, could change connectors and use same 12 cord and see very little gain

I will have to say this that if I was busy in production would change out for ease of connection. I use Type H due to the fact I started that way and use the same for 1/2 hose. They are what people here refer to as 3/8 but I used normal automotive stuff at Buds shop over the years.
The hoist installer had a 3/4 air gun and an automotive fitting, not much concerned.
There is a point it is relevant and that is one step too much for the tool to work proper but he wasn't using it to hit big bolts but to simply run nuts and 99% of the places he goes use this fitting.
If you are using a 1/2 air gun at home the loss factors are substantially less and there is no real user reason to unplug the hose,, actually not at work, maybe especially at work should have a tool whip where its needed.
Get a section of hose long enough to do tasks and easy to hand and screw it to the line so someone cant take it and the only connector being at he user end for the tool. This isn't always at the wall but often from a ceiling drop or down to hoist.

I see a local tire shop, the guy painted the place and is a great salesman but the utilities are a super pit all for the need of a few pieces of pipe. he doesn't need outlets every 4 ft but a drop across a ceiling and additional reel or 2. 2 or 3 100 ft air hoses and a 100 ft water hose strung all across shop floor every day.
Dipstick runs a V8 engine in a pickup for air in his own parking lot for 3 hrs to service a tractor tire cause they don't have a hose long enough, they do this every day.
