Small Universal Stopper - Drilled

Works just as it should. No complaints about it’s cons

Fits snugly in a six-gallon glass carboy, and compatible with 3/16 ID tubing. Works great (and no beer on the ceiling).

just got the majority of my brewing supplies in today without realizing that this needs to be ordered separately from the big mouth bubbler

Seals perfect and holds the airlocks tight. What else could I say?

Bought one to try it out and it fits nicely on the big mouth. Much better than rubber stoppers. I'll be buying more.

Only downside are the spots on top where crud can get in. But I think it's worth it for the flexibility. I tried a solid stopper and it wasn't as good.

this works really well with the big mouth bubbler.

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.

Absolutely great for working with carboys or erlynmeyer flasks.

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

Can serve more than one purpose. Handy when 'bubble-over- from overly active yeast spews whatever you're using in your system. Cheap compared to some others on the market.

Works as designed. Great fit for BMB lids. Would buy again.

After I transferred from my primary fermentation bucket to my carboy for secondary fermentation, it was my first time using this stopper and it wouldn't stay in place when I pushed it in. I panicked not having a back up and my LHBS was five minutes away from closing time. Not sure if it's because the inside of the carboy neck was wet, but I ended up having to use a muslin bag I kept from my recipe kit, sanitized it and placed it in pretty taut in the carboy opening and then plugging it with this stopper so it had something to grip making sure to leave some of the muslin sticking out so it wouldn't fall in. Going on day four and it's working just fine. I'm not sure I'd purchase this again in the future.

Like a charm.....

Good

Yep, works good!

It stops great!

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.

Works great in the Big Bubbler!

Works well!

Good product, less bulk than the solid stopper. I think this will do better at keeping its shape longer, creating a tighter seal.

Good product with a good description on the website.

Works fine

Haven't used this yet, but it looks like it will do just fine. Always a pleasure ordering from Northern Brewer. Great selection, fast shipping, everything is in good shape when it arrives.

Great beer. Easy to brew and great taste!

Great customer service. I have made 3 kits, choc milk stout, Irish red, and have just started drinking the orange petite, all have turned out great. These guys are the best.

Kettle, burner and fermentor arrive in perfect condition. I just brew this weekend with my new additions and everything was great and mint. No leaks in Big mouth bubbler, great burner performance and solid kettle. Thanks!

Hello the bung hole stopper fit perfectly and help keep the airlock in perfectly. I am really glad I got it.

A decent quality small stopper with a hole in it. In this case for a plastic 6 gal big mouth bubbler. It fit the lid perfectly and is currently keeping the nasty's out of 5 gallons of saison.

Product as advertised and works great.

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.

The small universal stopper fit my new big mouth bubbler perfectly!

Good quality product

Simple, durable and long lasting

It does what it is designed to do.

Works well, I had a time trying to get it to stay in at first but then it magically stayed. It has worked great for the last 2 ferments.

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

Small Universal Stopper works well.

It's a stopper

It works. Buy it.

works excellent

I received my order on time and packaged well. And I appreciate the reusable Ziploc style bags for the small items.

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

Good quality and shipped to me in a timely manner.

I have several of these. Sometimes they work, and sometimes they won't stay seated in the carboy. I've tried them wet, dry pushed in 1/2 way, pushed in all the way. I haven't determined yet if a particular one or two of them or just radonly not working. Like I said sometimes they work great, sometimes they dont.

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!
