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.

• Increased 150 ML capacity for the ability to inject sealant into higher-volume tires
• Patent-pending design featuring a drip-free one-way valve
• New press-on adapter connects directly onto Presta and Schrader valve stems for quick fills without threading or additional parts
• Design allows a precise fill of well-shaken sealant from the top for a convenient set-up with zero mess
