Take the mess out of installing and removing tubeless tires. The TSI-1 allows you to inject the perfect amount of sealant directly into mounted tubeless tires through the valve stem without removing the bead from the rim. The long thin tube is able to fully fit many Presta stems with removable valve cores, for neat injection and removal of all injectable tubeless tire sealants. The oversized syringe body features an easy-to-read gauge with fl oz and cc markings for precise sealant application.

- Syringe Capacity: 100cc (3.5 fl. oz)
- Tube size: 120mm (4.75") long x 3.5mm (0.14") diameter
NOTE: Some tubeless valve stems have a smaller opening than the TSI-1 tube. In these cases, the bead must be removed from the rim to remove the sealant from the tyre.
