KCHEX DRILLED AIRLOCK CAPS 4 38/400 FOR BEER WINE FERMENTERS & ONE 1 GALLON GLASS JUGS

They look like they will work perfectly.

Have to use Duct Tape to make hose tighter

I purchased these airlock caps after having scored a cache of one gallon glass jugs at a flea market. Noting that I couldn't get a great seal with any of the bungs and airlocks I normally use these caps were a lifesaver. They fit well to the jug, screwing on easily. With the airlock attached it seals perfect. I may purchase another set soon.

I like it more than the rubber style bung that I have to tie down with bands to keep from popping out due to pressure. However, when I add my airlock, it doesn't bubble unless I put tape or putty around the hole... which means that air can get into my brew if the co2 is coming from the space between the airlock and the cap. It's probably a very negligible amount, but I'd rather not risk making vinegar.

I use them for the galon 2nd wine fermentation.

Works great on 1gal jugs. Only issue some of the 2 and 3 piece airlocks would not fit tight in the hole Luckily I had some that fits

Better than the typical rubber stopper with a hole drilled in it. No problem with them working their way out and letting germs in.’ Mo I I ì

These are a lot sturdier than the one that came with my cider kit.
