Will these work on 16oz bottles?

Yes, as long as the spout of the bottle has measurements which are slightly less than the seal. I use mine for 4 and 8 inch bottles. They work really well for our products which are oil based.

Will these fit a 4oz jar?

From the ones I've ordered definitely not. They only fit like 10 gram containers
