Stans developed the Dual Action Repair for Tubeless (DART) tool to fix damaged tires faster, easier and better than existing plug tools. While traditional tire plugs try to wedge rubber strips into a puncture, the DART creates a chemical reaction with your Stan’s sealant to quickly form a permanent airtight bond. The DART Tool is designed to be extremely light, durable, and easy to fit into pockets and packs, while offering an ergonomic design that’s easy to hold and allows precision DART placement. The length of the rod is specifically calibrated to let you insert DARTs to the perfect depth every time, just by pressing until the head of the DART Tool contacts your tire. No risk of damage to rim or rim tape during a fast repair. The head of the DART Tool is double-sided and reversible, allowing it to hold two sealed DARTs on each side. This makes it possible to install two DARTs quickly when sealing the largest slices and punctures and even multiple punctures.
