## Description

Blue Cap for 6.5 Gallon Carboys and 3-piece airlock, Not For Use With Better Bottles

Review: Great product-fits a 6.5 gallon threaded-neck (acid) carboy snugly enough that I could pressure transfer to a keg with about 2 pounds of pressure (I would not recommend that, but I did it anyway). I would buy again if I needed another.

### ⭐⭐⭐ Review
*by P***O on 18 March 2023*

I did eventually get it on the carboy after SEVERAL attempts, finally getting it over the lip gently starting on one side and sliding the opposite side down the edge of a VERY slim and narrow blade angled outward, because it wouldn't ever go over the lips on its own. It's been down there a week. I'm afraid to touch it, definitely not stable - but I'm hoping the cap will stretch a little with repeated use. Outside of that - the concept looks good.
