Park Tool TSI-1 Tubeless Sealant Injector

With the Park Tool TSI-1 Tubeless Sealant Injector, filling tubeless tyres is child's play. With the TSI-1 sealant injector for tubeless tyres, you can inject the perfect amount of sealant directly into the mounted tubeless bike tyres via the valve stem without having to remove the bead from the rim.

The long, thin tube fits through many Presta valve stems with removable valve core and allows for clean filling and removal of all injectable tubeless sealants for bike tires. The large syringe body features an easy-to-read gauge with oz and cc measurement scales for precise sealant application.
