And here is what Stan’s has to say:
Stan’s NoTubes Sealant is a thin, low viscosity liquid that coats the tire interior and seals punctures quickly. Two ounces of Nalgene in a tubeless tire can repair punctures up to 1/4″ to keep you rolling. Nalgene 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 Nalgene 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
- Non-hazardous, non-corrosive, non-toxic
- Contains natural latex
- Stable down to -30 degrees Fahrenheit
- Designed to seal punctures up to 1/4
