Great price b Review: Quality bubblers! - Great for homemade wine making. I used these without the stopper on my primary fermenter and with the stopper on my secondary glass carboy. They are well made and work very well. I did notice the stoppers liked to slip up out of the neck of the glass carboy a little so I had to tie them down into the neck but this may be unrelated to the stopper itself. ## Features - WHAT'S INCLUDED: With this purchase, you'll receive two twin bubble airlocks and two universal-fit carboy bungs for managing fermentation of beer, wine, mead, or kombucha. FastRack airlocks are made from food-grade, transparent plastic—stronger and clearer for easy monitoring. The airtight design helps prevent oxidation, and the airlocks automatically release pressure during fermentation 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. - 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. - OUR COMMITMENT TO YOU: At FastRack, we stand behind the quality of our products and the trust our customers place in us. Your experience matters. If your order arrives damaged or incomplete, reach out—we’ll make it right. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00A6TRKO4 | | Best Sellers Rank | #10,907 in Kitchen & Dining ( See Top 100 in Kitchen & Dining ) #4 in Brewing & Fermentation Airlocks | | Brand | FastRack | | Brand Name | FastRack | | Color | Clear/Tan | | Customer Reviews | 4.6 out of 5 stars 13,855 Reviews | | Global Trade Identification Number | 00825392000052 | | Included Components | Airlock and Stopper (Pack of 2) | | Is Customizable | No | | Is Customizable? | No | | Item Dimensions L x W | 3.15"L x 1.97"W | | Item Form | physical component | | Item Type Name | Bubble Airlock and Bung (2pk) | | Item Weight | 30 Grams | | Manufacturer | Fermtech | | Manufacturer Part Number | B00A6TRKO4 | | Material | Plastic, Rubber | | Material Type | Plastic, Rubber | | Model Number | B00A6TRKO4 | | Number of Items | 2 | | Product Dimensions | 3.15"L x 1.97"W | | UPC | 628504292792 825392000052 | | Unit Count | 2.0 Count | ## Product Details - **Brand:** FastRack - **Color:** Clear/Tan - **Is Customizable:** No - **Item Weight:** 30 Grams - **Manufacturer:** Fermtech - **Material:** Plastic, Rubber - **Number of Packs:** 2 - **Product Dimensions:** 3.15"L x 1.97"W - **UPC:** 628504292792 825392000052 - **Unit Count:** 2.0 Count ## Images ![Fastrack Twin Bubble Airlock and Carboy Bung (2-Pack) | Fermentation Airlocks for Homebrewing Beer, Wine, Mead, and Kombucha - Image 1](https://m.media-amazon.com/images/I/41lj7thLfSL.jpg) ![Fastrack Twin Bubble Airlock and Carboy Bung (2-Pack) | Fermentation Airlocks for Homebrewing Beer, Wine, Mead, and Kombucha - Image 2](https://m.media-amazon.com/images/I/51Y-8lnz-yL.jpg) ![Fastrack Twin Bubble Airlock and Carboy Bung (2-Pack) | Fermentation Airlocks for Homebrewing Beer, Wine, Mead, and Kombucha - Image 3](https://m.media-amazon.com/images/I/512gF1jTHnL.jpg) ![Fastrack Twin Bubble Airlock and Carboy Bung (2-Pack) | Fermentation Airlocks for Homebrewing Beer, Wine, Mead, and Kombucha - Image 4](https://m.media-amazon.com/images/I/416iaYbMayL.jpg) ![Fastrack Twin Bubble Airlock and Carboy Bung (2-Pack) | Fermentation Airlocks for Homebrewing Beer, Wine, Mead, and Kombucha - Image 5](https://m.media-amazon.com/images/I/61ZDaeRR8XL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best price *by J***N on March 2, 2026* Works great. Great price b ### ⭐⭐⭐⭐⭐ Quality bubblers! *by T***Y on October 27, 2025* Great for homemade wine making. I used these without the stopper on my primary fermenter and with the stopper on my secondary glass carboy. They are well made and work very well. I did notice the stoppers liked to slip up out of the neck of the glass carboy a little so I had to tie them down into the neck but this may be unrelated to the stopper itself. ### ⭐⭐⭐⭐⭐ Works great - cost effect way to make your own fermenter lid *by S***A on September 11, 2023* I bough this to make a primary fermenter out of a 5-gallon bucket lid. It was super easy. Just had to buy the right grommet and drill a hole. Some measurements as I thought it may help others: Outside Diameter of the air lock stem is 7/16" (0.43" as measured by my caliper) I purchased a 3/8" nominal rubber grommet (0.375" inside diameter) for a nominal hole side of 1/2". I used a step drill to make a hole just slightly larger than 1/2". It may have been closer to 9/16ths. Step dril works great for this as you can size it up slowly to test your fit, and the step shoulders de-burr the hole. Installed the grommet, and pressed in the air lock. It is a tight fit and the rubber grommet is firmly, but not over-compressed. It has formed a tight air seal and the fermenter is bubbling as a I type. Air lock is a simple device that works great. ## Frequently Bought Together - Twin Bubble Airlock and Carboy Bung (Pack of 2) - Lalvin EC-1118 Wine Yeast (10 Pack) - Champagne Yeast - Make Wine Cider Mead Kombucha At Home - 5 g Sachets - Saccharomyces cerevisiae - Sold by CAPYBARA Distributors Inc. - Fermtech - Auto Siphon Mini with 6 Ft of Food Safe Tubing & Clamp - Easy Home Brewing, Winemaking Kit, Complete System for Beer, Wine, Liquid Transfer & Fermentation Tools - Perfect for Small Batches --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/276840-fastrack-twin-bubble-airlock-and-carboy-bung-2-pack-fermentation](https://www.desertcart.pe/products/276840-fastrack-twin-bubble-airlock-and-carboy-bung-2-pack-fermentation) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-05-18*
