This item does not fit on a portable air compressor. The male end is 3/4" thread not 1/4" thread size. May work great on a large compressor but not a Kensun Portable Air Compressor. I bought to fit on the Kensun, so that I do not have to screw the Kensun onto the tire valve stem. There is not a lot of room to get to the tire valve stem with the wheel cover on and needed a more convenient method. Unfortunately this does not fit onto the air compressor.
