Tubeless Sealant Injector

Take the mess out of tubeless tire setup and removal. The TSI-1 enables 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 fit all the way through many Presta stems with removable valve cores, for tidy injection and removal of all injectable tubeless bicycle tire sealants. The oversized syringe body features an easy-to-read gauge with fluid ounce and cc markings for precise application of sealant.
