Best tire inflator for dually tires

Ok I started this mess - here is how I finally fixed my dually tire issue. Oh first off the 1/4x1/4 fittings don’t work and so neither will the air chuck extension - at least for my air compressor. So the final solution was to buy 8 inch valve extensions . Don’t get ahead of me as here is what I did. I simply attach it to the valve stem then check air pressure and air up as needed. NOW I simply unscrew the extension and put it up. IT does NOT stay on the tire valve - it’s just a way to add or check air. Problem fixed and I don’t need a new air compressor. Sorry I made this way more complicated than it needed to be.

Thanks everyone
