Fits most juice bottles. Only had one jug of juice it didn't fit. Review: Nice Airlock - I've read a three piece airlock is the best type and I agree. You would think less moving parts would be better but I don't think so. This airlock seems cleaner and more efficient. I just today started using mine and time will tell. ## Features - WHAT'S INCLUDED: With this purchase, you'll receive a set os 2 transparent 3-piece airlocks and two drilled rubber stoppers—compatible with most standard carboys and fermenters for brewing beer, wine, mead, & more. Made from durable, food-grade plastic, FastRack airlocks offer excellent visibility of the fermentation process. The airtight design prevents oxidation & automatically releases pressure at room temperature without manual effort. - EASY & SIMPLE TO USE: Insert the assembled airlock into the hole of the rubber stopper that fits your current jug or carboy. Fill the Bubbler Airlock with water and insert the drilled stopper or bung to vent gasses during fermentation. The airlock cap should always stay on top when in use to allow gas to escape and prevent the water inside from quickly spilling out if tipped over. - HOW IT WORKS: Airlocks enable CO2 to be released during fermentation and trap oxygen from entering the fermenter. The bubbler style airlock is the preferred airlock for secondary fermentation, as it is possible to monitor the pressure inside the fermenter, and is the go to winemaking airlock. - DRILLED RUBBER STOPPER: FastRack bungs come with a pre-drilled hole in the center sized to fit all standard-sized airlocks. The rubber bung is tapered for a better seal holding the airlock securely in place. There is a curved lip on the bung to stop it from accidentally sliding into the fermenter. Our rubber bungs have many uses in fermentation; including beer brewing, cider and winemaking. - OUR COMMITMENT TO YOU: At FastRack, we stand behind the quality of our products and the trust our customers place in us.

The bottom of the flair is 1 1/8 in diameter and the widest point of the flair at the top is 1 3/8. The very top has a ridge which has a diameter of just over 1 1/2 inches but this portion can not be inserted into the bottle. **Q: I this airlocks compatible with better bottle (plastic) carboys?** A: No, they are too small. **Q: Does this fit into the Mason Re-cap? http://www.amazon.com/gp/product/B00JV1CV1A/ref=gno_cart_title_2?ie=UTF8&psc=1&smid=AJHGXY4OFIPO4** A: It will fit a 1 1/4" hole **Q: will this work on a .5 gallon plastic juice jug?** A: Thanks for shopping. This stopper is too large for a common plastic jug. You may want to consider a #6 or #6.5 rubber stopper for a common plastic jug with an inside opening diameter of 1-1/8in. Just measure the ID of your jug before purchasing to find the right size. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Successful airlock *by B***7 on May 13, 2026* I have made wine successfully with these.
