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.

I haven't used it yet because shipping was late and I had to freeze all my grapes.
Item as advertised, promptly delivered and would recommend it and Midwestsupplies.
I like this airlock because it is very easy to clean for reuse.
Works well, I put them on my fermenter with sweetstuff in it then add yeast and they go bloop bloop for a few days and happiness is made!! It's amazing I tell ya!
I have bought other airlocks and this one seems more durable than the others.
