Park Tool TSI-1 Tubeless Sealant Injector

Make mounting and dismounting tubeless tires easier. With the TSI-1, you can fill 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 tube fits through many Presta valve stems with removable valve cores and allows 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 filling of the sealant.

Features:

• Syringe capacity: 3.5 fl. oz. (100 cc)
• Tube dimensions: 120 mm (4.75") long x 3.5 mm (0.14") diameter
  
  

NOTE: Some tubeless valve stems have an opening smaller than the tube of the TSI-1. In these cases, the tire sidewall must be removed from the rim to remove the sealant from the tire.
