Brake Fluid Leak

I have used the vacuum pump method successfully on three difffeernt vehicles without doing anything to the bleeder valve threads.

i have too, but i have noticed tiny bubbles that i guess were from a little air getting sucked in from the loose bleeder threads. i guess it doesn't effect the vacuum bleeding, as what tiny amount of air that's getting in is outside the braking system at that point. it's never dawned on me to put any kind of sealant on the bleeder threads.
