How can you use a dually chuck with a portable tire inflator

Hi guys - I have a RAM 3500 Dually and want to carry a portable power pack/air compressor so that I can inflate/deflate my tires for use on the sand (and to generally have around in case of an emergency). The problem is that I can't reach the inner stem without a dually extension chuck like this one , but the chuck uses a 1/4" NPT thread (female) and all of the portable air compressors use a standard car/bicycle-style shrader connector like this:

I have no idea what I need to go from the car/bicycle-style shrader connector to the 1/4" NPT dually chuck or what to search for. And no, I don't want to replace the stems on the tires (that's what the chuck is for). Does anyone have any ideas? Thanks in advance for any tips.

Get some screw on stem extenders maybe?? They make a hose set too that screws onto your stems amd extends out so you can fill them easier, as I remember they equalize the pressure from the two tires as well.

You can either cut off the bike style and put a barb fitting on your dually chuck or thread one of these in the dually chuck and run either.


Menards has them too but only in a 1/8npt so you would need a pipe bushing too.


I swear I've seen them at Fleet and Cheat but I can't find them on their website.

Thanks John-e that first link looks like exactly what I need!
