Easy Access: 12mm Bent Tubeless Valve Stem
Stop struggling with tight clearances when checking your tire pressure. The Universal Parts Bent Air Valve Stem features a fixed 90-degree angle that projects the valve away from the hub, making it easy to reach with any standard air chuck. Designed as a direct OEM-quality replacement for Genuine Buddy and Chicago Scooter Co. models, this bolt-on stem provides a secure, leak-proof seal for 12mm rim openings.
Technical Performance Features
- 90-Degree Angled Design: Engineered to provide clear access for pressure gauges and pumps on small-diameter wheels where straight stems are blocked by the hub or brake components.
- Secure Bolt-On Installation: Features a threaded metal body with a removable locking nut and dual rubber seals, providing a much more reliable fit than standard pull-through rubber stems.
- 12mm Mounting Diameter: Specifically sized for rims with a 12mm valve hole, ensuring a precision airtight fit on a wide range of modern tubeless scooter rims.
- All-Inclusive Kit: Comes complete with a threaded plastic valve cap, valve core, and all necessary hardware for a professional-grade install.
