I have seen a YouTube video of bleeding with vacuum where they put
something on the bleeder threads to seal them. Sorry that I can't be
more specific, as there is a gazillion brake bleeding videos.

I've used HandiTak for that (and have heard that plumber's teflon tape
also works, but cannot confirm).

It deteriorates incontact with brake fluid (I was sloppy), but it seals well enough to
do a vacuum bleed.
