It fit and the air lock fit in the bung without any problems great product!!!May 22, 2013Just Right...Seals tight with little effort, easy to clean and sanitize, and cheap enough to have a couple on hand as spares.June 4, 2013The stopper for PET carboysFits 3-, 5-, and 6-gallon Better Bottles. These lightweight stoppers always make a snug fit in my carboys, and I'm never concerned about them worming their way out, as with other types of stoppers. No matter how many carboys you have, it's always best to have a few extra of these stoppers around.June 4, 2013great sealthis bung creates a very effective seal that is better than the rubber grommets. fits perfectly and i've never had an issue with this product.June 13, 2013BungThese fit the 6 gallon PET carboys I just purchased. Good fit, no problems.June 17, 2013Great for Better BottlesThis is the stopper included with a starter kit that uses a better bottle. They are also the correct size for use with PET plastic carboys. Perfect size, precisely drilled, nicely priced.June 22, 2013A must have for a better bottle.This stopper fits perfectly into the better bottle neck and the shape of it keeps it from falling all the way in. Worth the few bucks!June 28, 2013Works great on my carboysThese fit the 5-gal carboys perfectly...a good snug fit without a lot of effort. I have some other solid stoppers that darn near require a mallet to insert once the airlock is in place. Not with these. And they're easy to clean!July 1, 2013
