The Park Tool TSI-1 Tubeless Sealant Injector simplifies tubeless tyre maintenance by letting you inject sealant directly through the valve stem without breaking the bead seal.
The precision-engineered tube fits standard Schrader valves and many Presta stems with removable cores, delivering clean, mess-free application every time. The oversized syringe body features clear fluid ounce and cc markings, ensuring you apply exactly the right amount of sealant for optimal tyre performance. Whether you're topping up existing sealant or setting up new tubeless wheels, this tool eliminates the hassle of tire removal and keeps your hands clean throughout the process. Compatible with all injectable tubeless bicycle tyre sealants, the TSI-1 is an essential addition to any cyclist's maintenance kit.
