Stan's No Tubes Tire Sealant

The product that sparked the Tubeless revolution

Inside this simple bottle is the product that changed cycling. Today’s tubeless systems rely on the lighter, more reliable self-sealing performance of Stan’s Tire Sealant.

Just two ounces of Stan’s in a converted standard tire or tubeless tire can instantly seal punctures up to 1/4" so you can keep riding without interruption. Stan’s longest-lasting tire sealant is formulated to remain liquid in tires with even thin casings for up to seven months. Dry conditions may require more frequent monitoring of sealant levels, but the anti-freeze agents in our special formula allow Stan’s Tire Sealant to perform in temperatures as low as -30°F. One liter can convert up to 16 tires.
