The product that started a Tubeless revolution. Inside that simple black 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.

The #1 tire sealant on the market

Just two ounces of Stan's in a converted standard tire or tubeless tire can repair punctures up to 1/4" almost instantly to keep you riding. Stan's Tire Sealant is formulated to stay liquid in tires with even thin casings for up to seven years Arid conditions require more frequent monitoring of sealant levels, but our specially formulated antifreeze agents allow Stan's Tire Sealant to be used in such cold temperatures than -20°F.
