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 tire sealants. Features an oversized syringe body with easy-to-read gauge for precise application of sealant.

• 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 tire
