## Description

3-Piece Airlock and 6.5 Bung (3-pack)

Review: Good deal - These work great for my home winery with one gallon jugs.
Review: No issues reusing old gallon wine jugs for fermenting. - No issues, let's me do small batch fermenting in gallon bottles.

## Features

- AUTOMATIC TRANSPARENT AIRLOCK: FastRack airlocks are stronger, more transparent, and made of food-grade materials. You will easily see the entire fermentation process! Due to the airtight design of our fermentation airlock we isolate the air and prevent oxidation. Fastrack brewing airlock exhausts automatically at room temperature without manual intervention.
- 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.
- WIDELY USED: The fermentation airlock can be used in various fermentation projects to preserve food as well! The brewing airlock can be used to brew craft beer or wine, but also used for sauerkraut, kimchi, etc.
- SATISFACTION GUARANTEE: At FastRack we pride ourselves on creating products that can be trusted by our customers. Buyer satisfaction is our top priority, maybe, sometimes accidents happen during shipping. If anything is cracked or broken, please let us know and we’ll do our best to make sure you are 100% satisfied with our product and service.

## Questions & Answers

**Q: What is the overall height?**
A: Thank you for your inquiry. The airlock and stopper together are approximately 5 inches tall.

**Q: Will this fit a standard 32oz juice container at supermarket?**
A: Thanks for asking. These stoppers will fit a 1-1/4in opening just right. Take a measurement and let us know if this isn't the right size for you. We'll be happy to find the right fit for you. Thanks!

**Q: Do I need to put water in the cup?**
A: Yes.  There is a fill line, fill it to that line.  After some time some of the water evaporates so depending on how long you keep the airlocks on, you may need to add more water.

**Q: Does this fit a 3 gallon carboy**
A: Yes, this fits most modern 3, 5, 6, and 6.5 carboys.  A TIP:  The #6.5 is almost too small and the #7 is way too big.  If you put the 6.5 in and then the push in the airlock you can accidentally push the stopper into the carboy.  INSTEAD, fit the airlock to the stopper (Making it a little larger) and then push the assembly into the carboy.
