Stan's No Tubes
Stan's Sealant is the foundation of their tubeless conversion business, and arguably the best tire sealant in the cycling market. This specially formulated solution contains tiny sealing particles carried within a thin liquid, which allows the sealant to quickly and effectively seal punctures up to 1/4" in diameter. In most cases, the sealant provides a permanent fix for punctures.
Each 2 oz bottle provides enough sealant for one mountain tire, or two road tubeless or tubular tires. The convenient size of this bottle also makes it ideal for small repair kits or tool boxes. 16 and 32 ounce bottles are also available as a more economic option for multiple sealant applications. Stan's Sealant is low odor, non-hazardous, non-toxic and environmentally safe.
Stan's Sealant is suitable for use in tubeless, tubeless ready, tubular, and standard tires, as well as in tubes with removable valve cores. Shake bottle thoroughly in the inverted position before use to maximize sealing performance. Remove valve core and add sealant through stem or pour directly into the rim or tire. The sealant will remain liquid in the tire for 2-7 months depending on the climate and can be used in sub-freezing temperatures.
