Núcleos de válvulas No Tubes de Stan

The Stan's No Tubes Valve Core is a straightforward replacement core for tubeless valve stems — the small but critical component that keeps your tubeless setup airtight and serviceable. Sealant buildup and corrosion can compromise a valve core over time, making a fresh set a simple fix when you're troubleshooting a slow leak or sluggish inflation.

Designed for use with Stan's tubeless valves, these cores are a sensible thing to have in your kit before you're stranded needing one. A valve core tool makes installation clean and quick, though most pump heads and CO2 fittings include a built-in slot for the job.
