Fermentation TPE Rubber Stoppers – Drilled Bungs for Airlocks (#6, 6.5, 7, 7.5, 8-5-Pack)

Great little kit for brewing. I was worried about the silicone bugs vs rubber but it turns out they're actually really nice, without the rubber scent that come with the rubber bungs. I use these quite a bit and love em. Great price for this little kit. I'm really glad they added the little rubber pieces to place into drilled out lids and caps to add airlock to containers that weren't meant to be used as fermenter.

These fit great in a 1 gallon wine jug.

I am new to wine making. The listing gives size by number. I need a larger bung, and it was not in the pkg. If the ad had shown size by a ruler or metric, I would not have ordered this pkg. However the product is top quality, and I will keep them to possibly use for other things.

Work as planned

I've ordered from this seller 3 times. All 3 orders have come quickly, and have been exactly what I expected. I use them in gallon and half gallon bottles of shampoo for my dog bathing system. They work perfectly!

Unfortunately, not the size I need. But good stoppers.

Have bought these twice. Good quality, have zero complaints about these. Had to do measurements to make sure I bought the right size. Airlock fits tight and secure tightly in the carboy. Have noticed if the inside rim or the rubber is wet they tend to slip out of the carboy. Can be solved with making sure those are dry or taking a rubber band and wrapping around the finger loop and over top of the stopper. They are a little pricey in my opinion but should last a lifetime.

Work perfectly in my 6.5 gallon carboys

Clean, fits well. Works as intended.
