seals the deal
Bought these to seal an antigue gallon jug I use for Fermenting peppers, factory jar used wax paper, these fit exactly.Also when I ordered the sales rep. Was kind enough to tell me foam plates cut out will get you by, saved about week or two of fresh peppers.

I just purchased a brand new 6.5 gallon glass big mouth bubbler and figured id buy these to go along with it. The description states these are for the glass only units so I figured I was good to go. my order came in and the new glass bubbler came with the Big Mouth Bubbler® Universal Lid - Single Port SKU# 41829 which physically cant be used with these seals. IM assuming that at some point the glass big mouth came with a different screw on lid that these work on. so WARNING if your ordering a new unit contact support to make sure these will work.

Designed for the Glass Bubbler
I only have the glass bubbler, and these indeed work perfect for that. I use 2 or 3 at a time to get a good seal, but they cheap and easy to put in or take out so no problem. They should probably make them thicker in the future.Make sure you are not buying these for a plastic bubbler!

These are for glass only
Per NB staff: The lid gaskets are designed for the glass Big Mouth Bubblers. The lid for the plastic BMB was designed so it wouldn't need gaskets. When the blue lid ring is screwed on it will pull the white lid down creating the seal.

Doesn't fit plastic Bigmouth
I bought this at the same time as a Bigmouth Bubbler, thinking it would seal between the lid and carboy, but it is nowhere close to fitting, about 3/4 inch too large in diameter. Possibly it might fit a glass bigmouth, but there is no indication in the description that this is what it is intended for. Or possibly someone with a very steady hand could trim it down to fit, but as delivered, it is worthless for the intended purpose.

Will these fit the 1 gallon glass big mouth bubbler?

BEST ANSWER: Yes they will!
Hi There, do these work with the Little Big Mouth Bubbler as well?
M A on Dec 8, 2015
BEST ANSWER: Hello Martin,

Thank you for choosing Northern Brewer! Those gaskets will most definitely work for the Little Big Mouth Bubbler. Have a great day!
What is the ID/OD of the larger seal? I know these are not made for the plastic BMB, but if the gasket is bigger than the plastic BMB's mouth, I could always trim them down. I keep having to crank down on the lid of my BMBs and I'm reading the new universal lids can pop off during active fermentation.

Why didn't you guys just make a simple screw on lid w/ gasket for us plastic owners?
Justin T on Nov 9, 2015
BEST ANSWER: The ID is 4" and the OD is 6.5". I think the reason why we didn't make the gasketed plastic version is because of the narrow seat for the gasket in the plastic version. This is a bit of a Macgyver way of doing it but I have heard of guys wrapping the threads of the plastic BMB with saran wrap to get a better seal. But don't put my name down for that idea! Sort of the same deal with the universal lids

guys will wrap a bit of tin foil or saran wrap around the top of the jug over the lid a bit to keep it in place during active fermentation.
