Those bottle manufacturers would have no difficulty providing data
that would show for every so many gazillion bottles made, they may
have one failure.

So be it, when you are dealing with a volatile gas, even one failure
can not be accepted.

SFWIW, I use a plumbers torch when sweating copper.

Costs a tad more the Home Depot version, so keep it connected to the
bottle to protect the threads and to use the shut off valve.

YMMV
