I like that idea. Don't have to mess with drilling a pipe cap, etc. I
think I have most of the parts here at home.

Thanks, I.

I don't; at least not if that 'tank' is a Dewar flask instead of a
pressure tank. Most of the "nitrogen generators" I've had association
with have been LN2 systems.

Dewars have thin walls and insulation/vacuum between. They cannot take
significant loads or pressures anywhere on their surfaces.

Better to build a 'cradle' around the tank, and raise it into position
with that. (if it's a Dewar)

This if it is in fact an LN2 Dewar. The Airgas branch near me recently
got a *huge* O2 Dewar installed at their facility, something a good 30'
tall. The riggers screwed up and damaged the outer shell when setting it
in place with a crane and it took days and cost $$$ to get it repaired
and re-vacuumed.
