What you get: Three (3) bite valve connector pieces — a convenient spare set to replace worn or leaky valves and keep your hydration system hygienic. Sufficient quantity for daily use and periodic replacement. Why you need it: Replacing worn bite valves restores proper flow and prevents leaks or drips that waste water and create mess. These connectors let you replace the valve head without replacing the entire drinking tube, saving time and cost. Design & function: Each connector uses a simple orientation control: 0-degree = valve closed, 90-degree = valve open. The valve shape retains water and provides a steady, controlled flow for easy sipping while reducing splashes and spills. Materials & durability: Made from premium silicone and polypropylene (PP) for reliable, flexible performance. The materials resist tearing and maintain a clean water path so you can hydrate with confidence. Compatibility & ease of use: Designed to be easy to replace on most standard hydration pack drinking tubes—no need to swap the full tubing. Works across a wide range of hydration systems and outdoor gear. Maintenance recommendation: For hygiene and optimal performance, replace bite valves every 3–6 months or sooner if damaged. Performance highlights: Leak-resistant shape and fit Smooth, consistent water flow for sipping on the move Durable silicone and PP construction Typical use scenarios: Running or trail running: quick, spill-free sips during longer runs Cycling: steady flow that’s easy to access while riding Camping and travel: replace old valves to refresh pack hydration and avoid contamination Includes three bite valve connectors. Follow the 0-degree (closed) / 90-degree (open) orientation to control flow. Replace every 3–6 months for best results.
