Bite valves wear out. The silicone gets teeth marks, the seal stops working right, and suddenly your pack is dripping water down your back mid-ride. CamelBak's Big Bite Valve fixes that problem with a one-piece silicone design that has no moving parts to fail. The valve self-seals after each drink, which means no more wet jersey or leaked reservoir when the tube gets jostled in your pack.

The medical-grade silicone stays flexible in cold weather and doesn't get brittle after years of use. The design delivers higher flow than older CamelBak valves, which matters when you need to drain water quickly on a climb or refill at an aid station. Just bite down and the valve opens. Release and it seals. The connection fits standard CamelBak reservoir tubes with the 3/8-inch diameter.

If your current valve has started dripping or you're replacing one that fell off on the trail, this is the direct replacement. The valve works with all CamelBak reservoir systems except the Fusion Group Hydration models. Some riders keep a spare valve in their toolkit since the part weighs almost nothing and swapping it takes seconds. The valve connects to any CamelBak HydroLink component if you're mixing and matching parts between different packs.
