Please Quote. Vaseline is 100% compatible with O-rings.

Especially since fire codes

manuals explicitly state not to use it on some pumps that i
have. i can't tell the difference between materials of o-rings and would
rather not risk it.

They are speaking of mechanical seals. Do not use petroleum on
mechanical seals. Use glycerin

you paint the inside of your pumps?

No, but Silicone residue is mostly invisible and hard to get rid of.
If silicone use becomes standard procedure for lubrication around
the house then expect the residue to end up on painted surfaces.
If it ends up on painted surfaces you should expect problematic paint
jobs.
