Drilled gum rubber stopper. Used to provide a positive seal on fermentors. Drilled hole is compatible with standard airlocks.

The #6.5 stopper works well with our glass carboys and Big Mouth Bubbler PET fermentor.

Sticks Like Glue Review by Peter
I have no idea what the other reviewers are talking about as THESE rubber based stoppers are all I'll use. I think they are talking about the other plasticish stoppers offered with the carboys, they suck and won't hold until dried. These stick like they were glued in place............. which does cause a bit of an issue getting them out. BUT, I'd rather have an ultra great seal and have to dig it out instead of worrying about my stopper popping out. (Posted on 4/9/13)
Great for the price Review by Dan
I use these stoppers on all of my equipment and they never slip out and i have never had a sealing problem. (Posted on 3/23/13)
Both style airlocks slide in and out of hole through bung. Review by Steve
Neither of the two airlocks (both different types) I have purchased will give a seal and keep air contaminants out. Not sire what to do, but I will be looking for a different stopper/airlock combo. (Posted on 11/1/12)
