Stans Dart Tubeless Repair Refills - 6pack. The DART Refill includes six DARTs to refill the Stan’s DART Tool or Incredible DART Tool packaged in a resealable and biodegradable package. By using a flexible laser-cut material the DART conforms to nonuniform puncture shapes caused by the jagged and sharp edges of debris and obstacles found on trails roads and paths. Treated with a reactive solution the DART bonds with liquid sealant on the inside of a tubeless tire to form both a chemical and mechanical seal to permanently bond a puncture too large for tubeless sealant to repair on its own. For best results DARTs should remain well-sealed in packaging to maintain hydration of DART treatment.
