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)

Good advice. I'd add that if he does decide to put a side load on a
nipple, it should at least be sch80 or reinforced with a welded
sleeve. It's easier than most people think to snap a scd40 nipple at
the thread root by jerking it sideways. It happens every day when
farmers get careless useing a backhoe to pull water well pipe strings.
