Stan’s Universal+ Tubeless Valve Stems – Alloy – Extra Tall 37–46mm – Black – Pair

The Stan’s Universal+ tubeless valve stems are designed to deliver reliable airflow and sealing across modern tubeless wheel systems, including setups that use tire inserts. The multi-port airflow design allows air and sealant to move freely without clogging, even in high-volume or insert-equipped tires.

Riders choose the Universal+ valves when standard tubeless valves restrict airflow or struggle to seal on newer rim profiles. The extra-tall length makes these a proper fit for deeper-section rims without stacking extenders.

Key Features
• Two-piece alloy tubeless valve with black anodized finish
• Five airflow ports (four side, one bottom) for unrestricted air and sealant flow
• Presta valve core with TAP “Twist And Pull” cap
• Secure-lock valve nut for consistent rim sealing
• Rubber stopper shaped for modern tubeless rim profiles
• Compatible with tire insert systems
• Upgradeable to Exo-Core system by replacing valve core (kit sold separately)

Compatibility & Use Notes
• Extra Tall valve length fits rim depths of 37–46mm
• Designed for tubeless-ready rims
• Compatible with most aluminum and carbon tubeless wheels
• Works with standard tubeless sealants
• Sold as a pair
• Not intended for tube-only wheel systems

Service / Ownership Context
Valve clogging is a common tubeless issue; the multi-port design helps reduce blockages during sealant refreshes. When installing, ensure the rubber base sits flat against the rim bed before tightening the lock nut. Periodic removal and cleaning of the valve core helps maintain airflow over time.

Fit & Use Signals
• A good fit for tubeless setups using deep-section rims
• Commonly chosen for wheels with tire inserts or high air-volume tires
• Works well when standard valves restrict airflow
• Not ideal for shallow rims that do not need extra-tall valves
• Not the right choice for tube-based tire systems
