Dual Action Repair for Tubeless (DART) to repair large punctures and slices in tubeless tires faster; easier; and more reliably than existing tire plugs. Unlike traditional tire plugs that attempt to press rubber strips into a puncture; dual action DARTs create both a mechanical and a chemical seal. The DART anchors into a puncture while creating a simple and safe chemical reaction with your Stan s sealant to quickly form a permanent airtight bond.Repairs large punctures and slicesReacts with Stan�s sealant to form an instant, airtight sealNew woven, laser-cut material will not fray or pull out when ridingNew sonically welded reinforced plastic tip for added strengthWears off clean, no trimming needed, and can not be felt while riding, even on road tiresLightweight, compact tool fits the shape of your hand for more precise use and includes built-in valve core removerIncludes two pre-loaded DARTs for sealing multiple and larger punctures-
