TSI-1 Tubeless Sealant Injector

Product Information

The Park Tool TSI-1 Tubeless Sealant Injector makes managing your tubeless setup much cleaner and simpler. You can inject the perfect amount of sealant directly into your mounted tubeless tires right through the valve stem, completely avoiding the mess and hassle of breaking the tire bead. Its design is really smart, featuring a long, thin tube that easily navigates through both Schrader and most Presta stems equipped with removable valve cores, making sealant application or removal a breeze.

This injector isn't just about getting sealant in; it's also built for precision and durability. The oversized syringe body sports an easy-to-read gauge, ensuring you add exactly the right amount. Plus, the bidirectional plunger handles both injection and extraction, and there’s even a valve core remover integrated into the cap for convenience.
