OK, hears the deal.My 33 gallon Sears compressor now has 50 feet of new 3/8 air hose.The connector that is on the end of the hose that connects to the tool to the tank is also 3/8, but the connector on the end of the tool still as 1/4 inch.From the compressor to the end of the hose is all 3/8s. Why is my Florida Pneumatic 1/2 drive (Sears) having problems removing lug nut from my F150? The gun is rated at 580 lbs of torque. I suspect the 1/4 male end on the end of the tool. I still have 150 pounds in the tank and set the regulator at 125.With the trigger pressed I have 120 pounds of pressure at the regulator. Something is causing a restriction. Could it be the regulator?Wear will I be able to locate high flow fittings? Lowe's is clueless when I inquired about this.Same for Sears.My compressor is old but still functions well.From dead empty to shutoff is 7 minutes and change. The shutoff is at 150 pounds. I can't see purchasing a new 60 gallon compressor for the amount of work that I do.Not at this time anyway with the holidays approaching.Thank, Ken.


Stilkman added= These are good impacts, made by Florida Pneumatic (FP743A) , hardly any issues with them.

When I had a 5-horse 60-gallon 220 volt single-stage air compressor, I threw the regulator into a drawer because I never needed less than ALL THE PRESSURE I COULD GET.

I may not be understanding how the hose couplers you have are set up. And some quick-couplers just plain don't flow worth a ****. Pick up some genuine Milton "V" series for the 1/4" stuff, enough plugs for the air tools you use, and a coupler body for the end of your air hose. Check your 3/8 coupler--or remove it entirely and just thread the hose to the compressor tank like I did. Is it a real 3/8 coupler, or a 1/4" coupler with 3/8 threads? Every coupler you DON'T use is a benefit for air flow.

Put a pressure gauge on the air inlet of the air tool, so you can find out how much pressure is getting to the inlet of the tool while the tool is RUNNING. Anything under 90 psi is not good.

I have had that problem, I switched all couplers to 3/8" bodys kobalts and it was fixed.
The 1/4" body restricts the flow even just one.

Best part is most of my friends dont even ask to barrow air tools anymore.

Semi trucks use even bigger ones.

Turn the regulator up, 135 going in to the reel and the connector is only a fuzz and if 1 is bad 2 is worse. You will be losing near a pound a foot thru the hose and the lower the input the worse the problem. Change to a 25 ft hose, gain 20#,,, change connector maybe a pound.

120 psi at one end of a new 50' hose and a decent torque wrench, hmm sounds like something broken. Change out the hose and fittings and see what changes. if you have not used stuff before the new hose you might have a restriction or gun needs oil. E.g. do some basic trouble shooting. Put the (a) gauge at the tool and press the trigger.
I have only 125 psi and really crappy old gun on 50' of 3/8 and can get lug nuts to budge.

I agree, shoot some oil in the gun. This comp is at full power as its running an instant prior to shut off, if you want the most power and run time squeeze the trigger on the tool at this point. Make sure some adjustment on the tool isn't set wrong although many are full power in reverse. Had a tool a bug crawled in and stuck the screen almost completely.
The older hoses work better, they actually expand being on 24/7.

Prevost makes a "high flow" coupler and air plug in 1/4NPT. It flows approx 30% more air than the standard industrial profile air plug.

Lots of good suggestions with checking the gun & turning up the regulator or using a shorter hose.

Milton fittings should be readily available where you live. Northern Tool stocks V style. Rural King might.

As stated, get a Milton V style from Northern Tool. I just switched mine over, difference was pretty dramatic, my IR "Thunder Gun" impact now requires ear protection. Bonus is they won't work with common fittings so your buddies won't ask to borrow your air tools. Another benefit, the Miltons don't hiss air nonstop like the cheapie fittings.

That 'industrial' looks awesome, but why even consider that unless you're running a huge compressor? The Milton V is rated for something like 70CFM.

Well I think that the issue has been solved. The male connector going into the female connector has been slightly modified by my trusty drill press.Also all the tools that require large volumes of air have all been "reamed" I pull the trigger now and the tools twist and jump at the squeeze of the trigger. My Sears "Florida Pneumatic", Astro,Harbor Freight impact tools all have a much more responsive feel. Hopefully this procedure shall bear fruit in the near future.Thanks for all the advise and suggestions.Ken

Interesting the title of the OP thread had the solution even before "the problem" was solved. some things that make you go hmmm

Most of these tools have a regulator. I don't want them ripping out of my hands. while that's happening and tossing enegy not applied to work, one of the reasons for air tools isn't more power at every turn but its so manageable and can turn it down, use pressure and resistance to manage speed for smooth work, not to go like a bat out of hell when the speed limit is 55 anyway.
A lot of the detail work with a common 4 1/2 electric is done with the wheel coasting down, not ripping *** wide open. Same with air and wire wheel. If its truly running 13K then there isn't any load on it and got wayyyyyyyy more air than it needs. A little restriction, a whip0 at the tool doesn't hurt as long as overall demand is being met and may work as a choke at start or at trigger pull, many operators may not know you can squeeze it.
Hard to believe millions of cars and trucks been painted with standard automotive fittings but its so.

This is a little like AC wiring. The real additional load generated by garages is way over rated. It barely adds much to demand but for a bit of automatic air compression for the most part, this discounts specialized stuff but just simple shate, even hoist isn't a factor.
But Joe Homebody goes to wire this circuit and says, its got a 20A breaker on it and all of a sudden he sees 20A load, multiply it a couple times. None ever see 20A and that 6000 btu air con is running they see 20A cause its on a 20A circuit.
While air is usually 1 at a time in a home garage the object still isn't to drop the main as fast as you can but to get work you want done done. Once the lug nuts are coming off does it need more?

Is the Prevost high-flow different from the Milton V? The photos aren't clear, but they look similar if not interchangeable to me.

Yes, the Milton V--and the Prevost--are about the same ID as a 3/8" coupler, but with a 1/4 body.

I wish that Oetiker/RTC made a swing-coupler body for the Milton V (and Prevost???) style coupler plug. The Oetiker bodies have nothing in the way of the air. If I was using Milton M (also called Industrial Interchange) coupler plugs, I'd be using the Oetiker B1 coupler body. OTOH, the Milton V will still flow more air than an Oetiker coupler and an Industrial Interchange plug.
