Full Description
Design & Action
Plastic-tasting water ruins a good ride faster than a flat tire. The HydraFlex Tube Kit is a replacement hydration tube built from taste-free TPU that keeps your water clean and fresh, no matter how long it sits in your pack. This universal fit hydration tube works with USWE's Shape-Shift, Elite, and Compact Lumbar bladders using a plug and play connector that clicks in without fumbling around. The bright red tube resists kinking when you're twisted up on technical singletrack or stuffing your pack into tight spots, giving you consistent flow when you need it most.

FAQ
Will this tube fit my non-USWE hydration bladder?+
The HydraFlex Tube Kit is designed specifically for USWE bladders with plug and play coupling (Shape-Shift, Elite, and Compact Lumbar). It won't work with other brands unless they use the same connector system.
How do I clean the hydration tube?+
Pop off the quick disconnect connector, rinse the tube with warm water and mild soap, then hang it to air dry. The taste-free TPU material is easy to clean and won't hold onto funky flavors.
Does the tube come with a bite valve?+
Yes, the kit includes a high-flow bite valve that locks to prevent leaks when you're not drinking.
How long is the replacement tube?+
The tube measures 91.4cm (36 inches), giving you enough length to route it comfortably from your pack to your shoulder strap or helmet without excess tubing flopping around.
Can I use this tube in freezing temperatures?+
The TPU material stays flexible in cold weather better than standard tubes, but water can still freeze inside during winter rides. Insulate the tube or use an insulated sleeve for sub-freezing conditions.
I own a 3 liter pack from USWE that I love. The water flow is amazing. I recently purchased a different brand of hydration pack to fit my needs but the flow was horrible until I replaced the drink tube with USWE brand.
Its no ordinary tube
What can I say its a tube! It's a 36" long tube that is red in colour.
When connected to a bladder it delivers life-saving liquids that are designed to keep me hydrated while I wander aimlessly through the trees in an effort to balance myself while contemplating my life's choices.
As an added bonus the designers added a bite value to one end of the tube to ensure the life-saving fluid does not just leak everywhere as that would be bad.
