I drilled then filed a round hole ( about 12mm ) in the lid of a supermarket 5 liter water container . It all worked well. ### ⭐⭐⭐⭐⭐ Would buy again. *by M***S on 17 June 2026* I love these, good old fashioned airlocks. ### ⭐⭐⭐⭐⭐ Upgrade replacements *by A***E on 4 October 2022* My old s-bubble airlocks had become soiled and one of them even cracked while I was trying to clean it. These looked direct replacements, but proved to be more solid and have a very slightly larger circumference. This was not a problem as the bottom ends are tapered and therefore fit into my existing grommets. The airlocks have sharp edges on the seams where the two halves are welded together, and these would damage the grommets, but a few seconds with a file fixed that. I like the caps for the top ends, which will help keep them clean between brews. I just completed a batch of hop nectar and the airlock worked perfectly. ## Frequently Bought Together - 5 x Airlock S-Bubble Type with Grommets - 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. - Youngs Campden Tablets 50 pk (Sodium Metabisulphate) --- ## 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.at/products/91048042-5-x-airlock-s-bubble-type-with-grommets](https://www.desertcart.at/products/91048042-5-x-airlock-s-bubble-type-with-grommets) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-08-08*
