The first tubeless sealant in the world, formulated by our founder Stan in 2001 and still the number one choice of riders today. Recommended for all-around use, compatible with all tubeless road, gravel, and mountain bike tires

The Original formula is the best choice for providing reliable puncture sealant performance over a 2-7 month period, however arid conditions may require more frequent monitoring of liquid sealant levels. Anti-freezing agents allow for use in temperatures down to -20ºF.

One liter of Stan’s Original Tire Sealant can seal up to 16 tires, consult our sealant volume charts for more detailed guidance.
