We've gone through five different formulas to ensure TCS Tubeless Tire Sealant is the best option for quickly and reliably repairing punctures up to 6mm in diameter. Our unique formula hardens the sealant molecules at the puncture site, creating a flexible, long-lasting repair.

We've ensured that TCS Tubeless Tire Sealant can quickly seal a puncture caused by anything you might encounter on the trail. Mica particles seal punctures using adhesives instead of relying on the evaporation of harmful ammonia. This means TCS Tubeless Tire Sealant performs consistently in harsh conditions where other sealants struggle to solidify due to minimal evaporation.

TCS Tubeless Tire Sealant is available in four sizes: 4-ounce and 8-ounce bottles for mounting up to four tires, and larger 16-ounce and 32-ounce bottles for any workbench. All bottles are graduated in ounces and milliliters to easily determine how much sealant to pour.
