The Product that Started a Tubeless Revolution. Inside this 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 Tyre Sealant.
The #1 Rated Tyre Sealant on the Market.
Just two ounces of Stan's in a converted standard tyre or tubeless tyre can repair punctures up to 1/4" almost instantly to keep you rolling. Longer-lasting Stan's Tyre 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 Tyre Sealant to be used in temperatures as cold as -20° F. One quart (946ml) will convert up to 16 tyres.
