Comet Bite Valve

Bite valves wear out long before the bladder does. The USWE Comet 45° Bite Valve is the 10 g part that puts a leaky, chewed or grit-clogged mouthpiece back to new: pull the old valve off, push the Comet on, and you are drinking again.

What it is

A high-flow replacement bite valve with a 45 degree bend, a self-sealing silicone mouthpiece and a twist lock you can work with one hand. It is made in PP/POM and silicone and fits onto standard hydration drink tubes.

Who it's for

Anyone whose hydration pack valve has started dripping down their jersey, or who wants a spare in the kit bag before a big day. Mountain bikers, trail runners, gravel and adventure racers, and moto riders all wear through valves; on a dusty summer ride through the hinterland a fresh mouthpiece is the difference between a clean sip and a mouthful of grit.

Key details

• 45 degree angle: the mouthpiece points at you when the tube is clipped to your shoulder strap, so you drink without tugging the hose
• High flow: a big drink in a short bite, handy mid-race or on a long climb
• Self-sealing silicone: closes again after each sip
• One-handed twist lock: shut it off completely without taking your other hand off the bars
• 10 g: PP/POM body with a silicone mouthpiece
• Fit: slides onto standard drink tubes on USWE packs and most hydration systems

Looking after it

After a muddy or dusty outing, pull the Comet off the tube and rinse the silicone mouthpiece under warm water so the self-sealing slit closes cleanly. Lock it shut before the pack goes into storage.
