I was worried about the silicone bugs vs rubber but it turns out they're actually really nice, without the rubber scent that come with the rubber bungs. I use these quite a bit and love em. Great price for this little kit. I'm really glad they added the little rubber pieces to place into drilled out lids and caps to add airlock to containers that weren't meant to be used as fermenter. Review: Was Only multi size pack I could find,works great - 5 pk of bungs worked great, I was sick of measuring carboy necks, I have 4 that all take different sizes , this solved my problem,5 sizes in one pk, they are also nice rubber that stays put, not like those slippery silicone ones that fly out of the carboy. I Just wish they put a 5.5 in too, ( for 5L Italian carboys) ## Features - DRILLED STOPPERS: Drilled bungs with standard size to fit an airlock - VARIETY OF FITS: Drilled rubber stoppers fit into a variety of different brewing vessels, and each stoppers measurement is specified in the product pictures - HOMEBREWING ESSENTIAL: A must-have for all home fermenters and homebrewers - FERMENT YOUR FAVORITES: Use with an airlock to make beer, wine, mead, cider, sauerkraut, kimchi, hard kombucha, and so much more - PREMIUM MATERIALS: Made from TPE (thermoplastic elastomer), a durable rubber-like, recyclable material ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09L1NWYJD | | Best Sellers Rank | #58,956 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #55 in Lab Rubber Stoppers | | Brand | Fermentaholics | | Brand Name | Fermentaholics | | Color | White | | Customer Reviews | 4.6 out of 5 stars 622 Reviews | | Is Dishwasher Safe | No | | Is the item dishwasher safe? | No | | Item Dimensions W x H | 1.2"W x 1"H | | Item Weight | 0.18 Pounds | | Manufacturer | Fermentaholics | | Material | Plastic | | Material Type | Plastic | | Model Number | DrilledBungsStopper - P | | Number of Items | 1 | | Product Dimensions | 1.2"W x 1"H | | Shape | Cylindrical | | Unit Count | 4.0 Count | ## Product Details - **Brand:** Fermentaholics - **Color:** White - **Is Dishwasher Safe:** Yes - **Material:** Plastic - **Shape:** Cyclindrical ## Images ![Fermentation TPE Rubber Stoppers 4-Pack – Drilled Bungs for Airlocks (#6.5) - Image 1](https://m.media-amazon.com/images/I/61xuKWMbJrL.jpg) ![Fermentation TPE Rubber Stoppers 4-Pack – Drilled Bungs for Airlocks (#6.5) - Image 2](https://m.media-amazon.com/images/I/51jOz6HN7cL.jpg) ![Fermentation TPE Rubber Stoppers 4-Pack – Drilled Bungs for Airlocks (#6.5) - Image 3](https://m.media-amazon.com/images/I/71tWktUoMSL.jpg) ![Fermentation TPE Rubber Stoppers 4-Pack – Drilled Bungs for Airlocks (#6.5) - Image 4](https://m.media-amazon.com/images/I/61Ltaap-EmL.jpg) ![Fermentation TPE Rubber Stoppers 4-Pack – Drilled Bungs for Airlocks (#6.5) - Image 5](https://m.media-amazon.com/images/I/61OaumDOkaL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great, affordable little airlock kit *by A***R on November 24, 2025* Great little kit for brewing. I was worried about the silicone bugs vs rubber but it turns out they're actually really nice, without the rubber scent that come with the rubber bungs. I use these quite a bit and love em. Great price for this little kit. I'm really glad they added the little rubber pieces to place into drilled out lids and caps to add airlock to containers that weren't meant to be used as fermenter. ### ⭐⭐⭐⭐⭐ Was Only multi size pack I could find,works great *by R***P on April 22, 2026* 5 pk of bungs worked great, I was sick of measuring carboy necks, I have 4 that all take different sizes , this solved my problem,5 sizes in one pk, they are also nice rubber that stays put, not like those slippery silicone ones that fly out of the carboy. I Just wish they put a 5.5 in too, ( for 5L Italian carboys) ### ⭐⭐⭐⭐⭐ Work as intended *by J***M on April 30, 2025* Have bought these twice. Good quality, have zero complaints about these. Had to do measurements to make sure I bought the right size. Airlock fits tight and secure tightly in the carboy. Have noticed if the inside rim or the rubber is wet they tend to slip out of the carboy. Can be solved with making sure those are dry or taking a rubber band and wrapping around the finger loop and over top of the stopper. They are a little pricey in my opinion but should last a lifetime. ## Frequently Bought Together - Fermentation Rubber Stoppers Drilled Bungs For Use With Airlock (#7 Rubber Stopper - 4 Pack) - Fastrack Airlocks for Fermenting | Bubble Airlock for Wine Making and Beer Making | BPA-Free S-Shaped Airlock used for Brewing Wine, Beer, Pickles & more |Transparent Airlock Set Of 3 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/407475290-fermentation-tpe-rubber-stoppers-4-pack-drilled-bungs-for-airlocks](https://www.desertcart.com.ar/products/407475290-fermentation-tpe-rubber-stoppers-4-pack-drilled-bungs-for-airlocks) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-07-07*
