## Overview

The Fastrack Twin Bubble Airlock set features two BPA-free, food-grade transparent airlocks designed for airtight fermentation. Its automatic CO2 venting system prevents oxidation while allowing you to visually monitor your brew’s progress. Compatible with various fermenter sizes thanks to its flexible bung, this durable set is perfect for beer, wine, and food fermentation projects, backed by a strong customer satisfaction guarantee.

## Description

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.

Review: Just perfect - It only just arrived, so I only gave gotten to test the fit so far, but it's absolutely perfect. I'm brewing cider in a 23L glass fermenter. The bung I got from the homebrew shop just did not fit at all and I had to tape it down for the previous brew. This one fits perfectly, very securely, and the air lock fits just as securely. I was looking at caps and was astounded at their price in Australia. This fella will surely provide a better seal, though. And the hollow design means that it should fit a slight range of diameters with its ability to flex. Simple is best!
Review: Good product - Quality is good

## 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: If they are 90% chance this is made in china how can we know the plastic is bpa free?**
A: Don't see that it matters. Nothing passes through the device into the carboy and positive to static neutral pressure inside prevents air from entering. Zero contact means no chance of transfer.

**Q: Can the airlock be removed from the bung and used with other standard bungs?**
A: Yes, the twin bubble airlock can be removed from the bung.

**Q: what is the height of these from top to bottom?**
A: aloha it is 7 inches.Try making "mead" it is amazingly good even with regular yeast! Add raisins

**Q: Will this fit my 5 gallon class jug?**
A: Yes. The universal bungs that come with the twin bubble airlocks are designed for 3, 5 & 6 gallon glass carboys.
