OEM High Precision 16mm Leak-proof Umbrella Valves for Hydration Water Bottles Usage in Bulk Order

Overview:

Our OEM High-Precision 16mm Leak-Proof Umbrella Valves are engineered for reliable one-way flow control in hydration and sports water bottles. Manufactured from platinum-cured, food-grade liquid silicone rubber (LSR) via precision LSR injection molding and optional compression molding for specific geometries, these 16mm umbrella valves deliver consistent, drip-free performance, excellent chemical resistance, and wide temperature tolerance. Fully customizable in slit geometry, Shore A hardness, color, and logo, we support prototyping through high-volume production with one-stop OEM services.
