The Product that Started a Tubeless Revolution
Inside this simple bottle is a product that changed cycling. Today's tubeless systems rely on the lighter, more reliable, self-sealing performance of Stan's Tire Sealant.

Longer-lasting Stan's Tire Sealant is formulated to stay liquid in tires with even thin casings for up to seven months. Arid conditions require more frequent monitoring of sealant levels, but anti-freezing agents in our special formula allow Stan's Tire Sealant to be used in temperatures as cold as -30° F. One quart will convert up to 16 tires.
- First choice of riders around the world for tubeless conversion and flat prevention
- Seals punctures up to 1/4-inch (6.5mm) quickly
