The original seals will get black over time from what could be mold. Yes, these must be removed and sanitized often. After a while the black is just imposible to remove and the seal must be replaced. These fit well and did the job! ### ⭐⭐⭐⭐⭐ Soze fits! *by on Reviewed in the United States July 6, 2026* Size fit just right! Love it. ### ⭐⭐⭐⭐ If you're careful it works *by on Reviewed in the United States August 16, 2024* Not much out there for Hydro Flask gasket replacements (don't know why). It does not have the raised edge of the original, but the silicone is thicker and should offset this problem with a tight squeeze of the lid. The problem is that the measurements are of the outside circumference is a bit smaller than the original. The inside measurement keeps it very tight. So if you slowly and evenly press down it sits well. If you push too far on one side it twists. ## Frequently Bought Together - Greant 6 PCS O Ring Compatible with Hydro Flask Wide Mouth Coffee Lid, Rubber Seal Compatible with Hydroflask Lid, 2 inch Flip Lid Gasket, Compatible with Hydro Flask Gasket Seals - Hydro Flask Wide Mouth Lids- Accessory for Wide Mouth Water Bottle - Hydro Flask Flex Boot - Accessory Silicone Water Bottle Protector - Dishwasher Safe, BPA-Free, Non-Toxic --- ## 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.kr/products/498481700-greant-6-pcs-rubber-seal-for-hydroflask-wide-mouth-flex](https://www.desertcart.kr/products/498481700-greant-6-pcs-rubber-seal-for-hydroflask-wide-mouth-flex) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-08-22*
