The Park Tool TSI-1 Tubeless Sealant Injector provides a mess-free method for tubeless tire setup and maintenance. With a long, thin tube, the TSI-1 makes it so you can inject and remove sealant all the way through a Presta stem with a removable valve core. No more sealant bubbling back and gunking up the valve. Park Tool quality, it features an oversized syringe body and easy-to-read volume measurement marks.

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.


  • Long, thin tube fits into Presta stem
  • Oversized syringe body for solid grip
  • Easy-to read measurement marks
  • Works with most major brands of sealant

Capacity: 3.5 fl. oz (100cc)
Tube Dimensions: 4.75 x 0.14" (120 x 3.5mm)
