Perfect Fit
I use these with my 6.5 gallon Big Mouth Bubbler and they help make a great seal.

Good Quality. Snug fit.
Just what I needed for the Big Mouth Bubbler. Have used it for two batches already and it worked great!

A major improvement over the old rubber stoppers!
Stays in place and doesn't try to slide out. It fits glass carboys and blue lidded big mouth bubblers. I had to by three replacements, because my brew club preferred to use them on their fermenters.

Great bung, even when you insert things into it!
Never had any issues, used in a variety of carboys. Not sure what some of the other people's issues are all about. Sometimes ya just gotta play with your bung until you find out what works for ya!

All stopped up.
Honestly? It's a stopper. It's drilled correctly and it fits. What more can you ask for from your bung-hole protective device?

Works so far
Gotta be dry for it to stay in the carboy...otherwise it just pushes itself out immediately. Only used it 2x so far and is holding up fine. Cheap and it works.

It's a stopper
The product is compatible with the lid to the Big Mouth Bubbler® Plastic 5 gallon Fermentor - which is what I needed.No defects with the product.

is this a good choice for the Big Mouth 6.5 gallon bubbler (PLASTIC)?
Thomad B on Jan 4, 2017
BEST ANSWER: I have used these with both the old style screw on lid and the new style push down lid and they work great.
I want to use this for blow off tubing. What size would I need that fits into this?
S B on Dec 27, 2015
BEST ANSWER: The 5/16" tubing will fit VERY tightly into the hole on the stopper, and 5/8" tubing will fit snugly over the center part of those stoppers, making a very good blow-off assembly.
