Description
Park Tool delivers their own take on the Tubeless Sealant Injector, with the shop mechanic in mind, but ideal for any rider who prefers to sealant off the garage or kitchen floor. it was developed to take the mess out of tubeless tire setup and removal. The 3.5 ounce capacity 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 needle-like 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 TSI-1 features an oversized syringe body with easy-to-read gauge for precise application of sealant, and an overall design that allows you use the syringe with one hand. There are some stipulations as far as what sealants will work, and it often comes down to whether or not the sealant has crystals or flakes mixed in, as these can clog the tube during use.
