The tire-filling end on a car wash compressor won't work.
You sure about that? You wouldn't even have to remove the nipple? :hmm:
Never tried it myself, it just seems like it would work, it would probably bugger up your nipple though...
Pretty sure. Almost positive but I have never tried it.
I was a mechanic for over 25 years and have a LOT of experience with valve stems and hose ends.
If you had a special nipple with a valve stem on the top it would work great! There is no way I can see that you would get any sort of a seal on a regular nipple or be able to get any appreciable amount of air to flow into the nipple to begin with.
A tire-filling air chuck just isn't built that way. There is a metal nub in the center that pushes down on the valve stem's core while at the same time being pushed back into the chuck. This opens the air flow in both. Meanwhile there is a rubber seat in the chuck that seals against the threaded lip of the valve stem to keep pressure in.
The flash hole in a nipple is smaller than the check valve stud inside the tire chuck and there is no place for the rubber seat to seal against. If you tried to use a tire air chuck you would blow air out of the hose but it wouldn't pressurize the bore.
If you were to hold a rubber valve stem tightly over your nipple and then use the tire chuck on the valve stem it MIGHT work.
