Stan's Tubeless Sealant Injector

Many things in the cycling world have changed since we released our first version of The Injector in the early 2000s. To offer tubeless users an injector that reflects the needs of modern tire sizes and the higher volume sealant fills required for a puncture-free experience, we are proud to offer our new Tubeless Sealant Injector.

VOLUME INCREASED TO 150ML
Larger volume gives you the ability to inject sealant into today's higher volume mountain, gravel, and road tires with a single fill

NEW PRESS-ON ADAPTER
Presses directly onto Presta and Schrader valve stems for quick fills without threads or additional parts

PATENT PENDING TOP-FILL, DRIP-FREE SYSTEM
A cross-slit valve in the fitting combined with a unique air relief channel in the injector body allows for a precise fill of well-shaken sealant from the top for a convenient, zero-mess setup
