## Questions & Answers

**Q: will this fit a regular 5 gallon plastic water jug?**
A: It does fit a five gallon jug but it doesn’t totally seal. I had to wrap the base with electrical tape so it would bubble. Not a very tight fit.

**Q: will this fit a 5 gallon plastic water dispensing bottle?**
A: It does fit and seems snug but leaks at the seal. You’ll need some ingenuity “tape” to seal it up tight.

## Customer Reviews

### ⭐⭐⭐⭐⭐ I would buy again.
*by  on Reviewed in the United States 24 January 2026*

Worked like it was supposed to. Sealed well. Good price. Durable. Make sure to leave room in your fermenting vessel for some foaming. Pushed solids up through bubbler, plugged it up, built pressure, blew plug from carboy (strawberry wine) and sprayed sugary juice all over the garage ceiling and my motorcycle

### ⭐⭐⭐⭐⭐ Great airlocks
*by  on Reviewed in the United States 6 March 2025*

I was skeptical of these before they arrived, but they functioned well, sealing properly to the water bottles

### ⭐⭐⭐⭐⭐ Worked...
*by  on Reviewed in the United States 13 June 2022*

5 gallon batch of cherry melomel I made in a recycled 5 gallon plastic water jug came out just fine for the four to six weeks it was in there. Couldn't get over the feeling that this thing might leak only because the bottom edge doesn't seem to tightly hug the top of the gallon container. But no obvious issues with the product so I guess it was fine. Wasnt sure what the purpose of two openings (different sizes) on top was, but again, it did the job.
