Stan's Sealant is a thin low viscosity liquid that coats the tire interior and seals punctures quickly. Two ounces of Stan's in a tubeless tire can repair punctures up to 1/4" to keep you rolling. Stan's Tire Sealant is formulated to stay liquid in tires 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 -30deg F. One quart can convert up to 16 tires.Suitable for use in tubeless tires and standard tubes
