About Park Tool Tubeless Sealant Injector (TSI-1)
Take the mess out of tubeless tyre setup and removal. The TSI-1 enables you to inject the perfect amount of sealant directly into mounted tubeless tyres through the valve stem without removing the bead from the rim. The long, thin tube is able to fit all the way through many Presta stems with removable valve cores, for tidy injection and removal of all injectable tubeless bicycle tyre sealants. The oversized syringe body features an easy-to-read gauge with fluid ounce and cc markings for precise application of sealant.

Features
Syringe capacity: 3.5 fl. oz. (100 cc)

Tube dimensions: 120mm (4.75") long x 3.5mm (0.14") diameter

Note: some tubeless valve stems feature an opening that is smaller than the tube of the TSI-1. In these cases, the bead must be removed from the rim in order to remove sealant from the tyre.
