I just bought my first air compressor; Campbell Hausfeld 2 Gallon Mini Twin-Stack Air Compressor with 1 1/4-Inch 2-in-1 Brad Nailer / Stapler Kit. So far I've been able to figure out how to operate the machine, but I'm a little lost on the coupling sizes.

According to my manual (for the stapler / nailer) it says to use a 3/8" air hose (for min air pressure of 150 psi) or a 1/2" air hose (for 50' run or longer). I measured the width of the hose that came with my compressor and it's 1/4". The threaded ends measure 1/2". Now I'm unclear about using the hose because obviously it's neither 3/8" or 1/2" (like the manual recommends). This seems odd because it is the hose they included with the compressor.

Also, the manual for the gun says to use a 3/8" quick plug (1/4" NPT threads) with an inside diameter of .315" (8mm) on the tool and a 3/8" quick coupler on the air hose. I measured the plug that goes into the gun (which has an end that snaps into a quick connect plug) and it is 1/2". The quick connect coupler that came with the compressor is also 1/2" (on both ends).

I am measuring the width of the threads. Maybe I'm not measuring correctly? I'm completely unclear what is what with this thing because the measurements I've taken do not match with those recommended by the manual. So I wondering if you can shed any light on this for me. I would appreciate any help you could offer.

Thank you.

I run 1/4" (ID) hose on my compressor and it works fine. Most common size hose you'll find. 1/4" pipe thread fittings are also the most common you'll find. They have ~1/2" OD. Maybe if you are planning to run a sand blaster or other high CFM device, 1/4" hose and fittings are fine:

you know, you could buy a paintball tank like a 45cu 3000 psi tank and regulate it down to the pressure you need for something portable.
