I don't think you have to worry about the tank.
Truck shops use a similar tank with a 1&1/4"+ outlet size line and a dump
valve.
They point the discharge tube at the rim / tire bead area ofa newly mounted
tire and 'dump' the contents of the tank in about a half second.

What you are doing sounds tame by comparison.

Indeed! Thank you for the reference. It's particularly interesting to
see that some of those carry tanks they're selling for that purpose are
aluminum to boot. This is reassuring.

I should have noted too that what I called my "carry tank" is better
called "portable". It's 50 pounds and ASME rated, the same tank Campbell
Hausfeld uses on their portable contractor compressors, not one of those
non-code tire inflator cans they sell at hardware stores.

Thanks,

Adam
