Park Tool TS-1 Tubeless Sealant Injector

The Park Tool TSI-1 is a professional-grade sealant injector designed for the clean and precise setup of tubeless tire systems. This syringe-style tool allows you to inject sealant directly through the valve stem, eliminating the need to unseat the tire bead from the rim. It is the definitive solution for riders and mechanics who want a mess-free way to maintain or refresh their tubeless setup.

The injector features an oversized body with a clear, easy-to-read gauge that holds up to 100 cc (3.5 fl. oz.) of fluid. Its long, thin tube is specifically designed to fit through most Presta valve stems with removable cores, ensuring the sealant reaches the tire interior without clogging. This durable tool is compatible with all injectable sealants and simplifies both the installation and removal of tire fluids.
