Park Tool Syringe TSI-1 Tubeless sealing milk injector

Make the installation and removal of tubeless tires easier. With the TSI-1, you can inject the perfect amount of sealant directly through the valve stem into mounted tubeless tires without removing the tire bead from the rim. The long, thin hose fits through many Presta valve stems with removable valve cores, allowing for clean filling and removal of all injectable sealants for tubeless bicycle tires. It features an oversized syringe body with an easy-to-read measurement scale for precise sealant filling. Specifications: Syringe capacity: 3.5 fl. oz. (100 cc) Hose dimensions: 120 mm (4.75") long x 3.5 mm (0.14") diameter. Note: Some tubeless valve stems have an opening that is smaller than the hose of the TSI-1. In these cases, the tire bead must be removed from the rim to extract the sealant from the tire.
