What diameters of openings (in inches) will this fit?
Roy Westerberg on Feb 25, 2022
If you use this with a blow off tube, what size diameter hose do you need?
Christopher Silva on Mar 3, 2021
BEST ANSWER: 5/16 fits quite snug, usually a couple sprays of sanitizer helps ease it in.

It works and would do for most home brewers
Works fine but prefer solid plugs. But works ok.

BIG BUNG
Did not fit my small batch fermenter. My fault, I didn't pay close attention to the description.

Great
Works great. I like the low profile, plus it catch a little if it bubbles out. I have a few in different sizes. If this is the smaller size they can also be used to fit smaller one gallon jugs ( wine bottles) by putting in hot water for a while and making them soft enough to force in the smaller opening. Once they cool they are permanent. I have always used this style and never needed to tied down my airlocks so they don’t pop out.

Excellent so far and I don't expect any issues. I don't use any old rubber bungs anymore. Very pleased.

Very hard rubber, almost like plastic
This rubber is much too firm to seal in a hole that isn't also tapered the exact same way as the stopper. The very thin straight-walled hole in the lid of my 1gal Fermonster did not seal against this hard rubber stopper.
I didn't test if it fit my airlocks well.

Works good for 10-15gallon barrel bungs
I have a few misc sized barrels with medium bungs that tend to accept #10 - #10, I started buying these because it was obnoxious to figure out what bung goes where, when these are universal. Also fits my Fermonster just fine. Good to have a couple in the brew house.
