Disgusted

There was a previous discussion on here or Tool forum about air pressure and volume for impact tools. I have a portable air tank with a female air fitting which I put on to pump up the tank with. My 1/2 inch impact tool is an Ingersoll Rand 235. I took it, the air tank with about 110 pounds pressure, a 1/4 inch Harbor Freight coil up air hose and the other usual tools to the tractor and took off the wheel. No problems, but by the last lug nut the air wrench was slowing down. When I put the wheel back on after lightening my pocket, I took note of the air pressure. Start 110 psi, after wheel back on 75 psi. Lugs were tight enough to drive home on, haven't put the hand wrench on them yet.

BTW, someone else locally was having trouble with pressure for his 3/4 inch impact tool and he went to larger fittings than the 1/4 inch I use.

Rick, someone else has the 3/4 impact, he has either changed to 3/8 or is in the process. I don't have a 3/4, though I may borrow his in a pinch.

Thanks for replies.

The fittings I use I believe are commonly called "3/8" automotive fittings". They are roughly half again bigger than the 1/4" fittings.

My painter buddy recommended these for painting with my HVLP gun. Personally my paint skills still suck so I didn"t see any difference. But at high pressure they will move a lot more air. You could buy one set and see if your impact wrench runs better. I dont have a 3/4" yet so cant tell you.

They are still 1/4" npt so no adaptors are needed to switch over.

At one time I found them at Home Depot. But any local tool shop that has air tools carries them.
