Many things within the cycling world have changed since we released our first iteration 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 fill of sealant required for a flat-free riding experience, we’re proud to offer our new Tubeless Sealant Injector. Note: for use only with Stan's Original Tubeless Sealant, not compatible with Stan's Race Day Tubeless Sealant formula. VOLUME INCREASED TO 150 MLLarger 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 ADAPTERPresses directly onto Presta and Schrader valve stems for quick fills without threading or additional parts PATENT-PENDING TOP-FILL, DRIP-FREE SYSTEMA cross-slit valve in the fitting paired with a unique air-relief channel in the injector body allows a precise fill of well-shaken sealant from the top for a convenient set-up with zero mess BRANDED HANG-PLUGIncluded for hanging on your workbench or mess-free storage in your toolbox
