When it comes to any type of pipe or tubing connections, I've generally preferred [the right] tape over compound from a tube for several reasons. It's not as messy, it stays where I put it, doesn't smear or run, doesn't care about gravity when I'm working overhead, easy to remove if I need to start over, and I can tell if I've put on the correct amount even in bad light. Also the tape doesn't go bad after opening if it sits for months between uses (I hope).

I'm certainly open to correction if Loctite's tube compounds turn out to be superior to tape especially for the high pressure connections.

Just to be clear, you are talking about HP air for blowing ballast and
not your O2 lines, correct? If so, my choice would be teflon tape. The
loctite 567 is going to seal and "lock" the fittings which is overkill
for tapered threads. Fitted correctly, tapered threads are not going to
come apart unintentionally. However, it sounds like either product will
work for the application and they likely only reference both to provide
a choice.
