Doesn't leak. ### ⭐⭐⭐⭐⭐ Great fit, no leaks *by S***E on July 22, 2026* They fit my older hydroflask bottles perfectly. Pop open easily when you push the button, and no leaks. Love the flexible carry handle too. ### ⭐⭐⭐⭐⭐ Perfect fit *by L***E on July 14, 2026* Had to replace my old lid (pictured on the right). This fit perfect, and works as stated. The plastic is smooth and the color is black. I put water in the bottle and turned it upside down and there were no leaks. Very comparable to my other bottle neck (length of a size double a battery) and easy to wash without needing a bottle brush. ## Frequently Bought Together - EIPOSAU Auto Flip Lid for Hydro Flask Standard Mouth Bottle, Spout lid for Iron Flask, Fits for Simple Modern and Most Brands, Replacement Lid with Button Lock, Black - Hydro Flask Stainless Steel Standard Mouth Water Bottle with Flex Cap and Double-Wall Vacuum Insulation - Hydro Flask Standard Mouth Lids- Accessory for Standard Mouth Water Bottle --- ## 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.kr/products/645547657-eiposau-auto-flip-lid-for-hydro-flask-standard-mouth-bottle](https://www.desertcart.kr/products/645547657-eiposau-auto-flip-lid-for-hydro-flask-standard-mouth-bottle) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-08-02*
