Hydraflex Drink-Tube Kit

What Our Gearhead® Experts Are Saying:

"I have been running the Hydraflex Drink-Tube Kit in my USWE pack for a full season of mountain bike rides, and the kink-free construction is the detail that sets it apart from every generic tube I've used before. On long descents where the pack moves around constantly, the flow stays consistent, and the twist lock keeps things dry in the pack when I am not actively drinking."

Hydration management on a long mountain bike or gravel ride is one of those things that only becomes obvious when something goes wrong, and a kinked or low-flow tube is exactly the kind of friction that compounds over a four-hour effort. The USWE Hydraflex Drink-Tube Kit is the replacement that eliminates that problem, built from highly flexible TPU that routes cleanly from a compatible USWE bladder to the valve without kinking, regardless of how the pack shifts on rough terrain or during technical descents.

The High-flow Blaster bite valve is the component that makes the biggest difference at pace. The high-flow design delivers a meaningful volume of water per sip so you can hydrate efficiently without pulling over or slowing down, and the self-sealing construction closes the valve automatically after each drink so there is no dripping or leaking between sips. The twist-on/off feature locks the valve completely when the tube is not in use, which matters on rides where the tube end is clipped to a shoulder strap and exposed to whatever the trail is throwing at the front of the pack.

At 35 inches, the tube length works for most pack and rider combinations without excess slack, and the 6mm diameter keeps the profile narrow enough to route through standard tube guides and clips without forcing anything. The Plug N Play connector makes bladder swaps and tube replacements fast enough to handle at a trailhead without tools, and the fully BPA and PVC-free material spec means it is a component you can feel good about putting between your water supply and your mouth on every ride.
