I have an Anderson Metals brass tube fitting, reducing hex nipple, size 1/2" male x 1/4" male to fit it to my Paasche compressor because it fits. was defective and finally blew me away. This item has arrived and the 1/2" side has a 5/8" ID therefore the outside diameter is larger, due to physical reasons. So not even close to 1/2 inch, whichever way you look at it.
