The Dual Action Repair for Tubeless (Dart) System offers a better way to repair damaged tubeless tires. Specially treated darts not only plug large cuts and holes in your tires, but they also react with Stan's sealant to create a permanent, airtight seal. This refill kit includes five darts and a holder that makes reloading your dart tool quick and easy, all in a compact, sealed container.
