Park Tool - TSI-1 - Tubeless Sealant Injector

Park Tool TSI-1 Tubeless Sealant Injector

A syringe for putting sealant into a mounted tubeless tyre through the valve, without breaking the bead. The long, thin tube fits through Schrader valves and many Presta valves with removable cores, and it'll pull sealant back out too. The 100cc body has cc and fl oz markings so you can measure the dose. Park has tested it with a long list of sealants including Orange Seal, Stan's, Muc-Off and Peaty's. Some valve stems have a smaller opening than the tube, and with those you'll need to unseat the bead to remove sealant. A replacement tube is on this listing too.
