The 3-Piece airlock is the best choice for the primary fermenter, since it comes apart for easy cleaning in the event of a blow-off.
Fill to the line with boiled water or sanitizer to create a closed fermenting system that allows CO2 to escape, but does not allow air back in to contaminate your beer or wine.

great lock,
only downside is it turns into a fruitfly trap so better have a few extra locks on hand to swap in with a clean one
