Stan’s NoTubes 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 -30° F. One quart can convert up to 16 tires. Suitable for use in tubeless tires and standard tubes Designed to seal punctures up to 1/4" Stable down to -30 degrees Fahrenheit Non-hazardous, non-corrosive, non-toxic Contains natural latex
