Perfect for a Longworth chuck! ### ⭐⭐⭐⭐ 4.0 out of 5 stars Great value!!! *by E***T on Reviewed in the United States on September 27, 2020* The media could not be loaded. Great value and work great for my glass 1-gallon jugs, for the most part, they fit pretty snug in the gallon jugs and some half-gallon jugs. I negative is that sometimes during the initial wine fermentation process, the gases push the stoppers and pop out causing spillovers. Also, when affixing the airlocks you get rubber residue and shavings. It's important to remember to wash them thoroughly after attaching the airlocks. Other than thank they work great and are a fantastic value. --- ## 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.us/products/218358576-20-pack-drilled-natural-rubber-stopper-6-solid-rubbers-stoppers](https://www.desertcart.us/products/218358576-20-pack-drilled-natural-rubber-stopper-6-solid-rubbers-stoppers) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-26*
