What Makes Stan's Original the Go-To Tubeless Sealant?

Stan's Original Tubeless Tire Sealant is the product that put tubeless cycling on the map, and it's still one of the most trusted sealants in the sport. The thin, low-viscosity formula coats the interior of the tire and seals punctures up to 1/4 inch quickly, keeping you rolling without stopping to swap a tube. Two ounces is all it takes to handle the most common trail and road hazards, and its proven chemistry has earned the trust of mechanics and riders across every discipline.

Formulated to stay liquid in tires for up to seven months, Stan's Original includes anti-freeze agents that keep it effective down to -30F, making it reliable in cold and arid climates alike. One quart converts up to 16 tires, and it's available in sizes from a 2oz bottle to a full 1000ml, so you can grab exactly what you need whether you're doing a single setup or stocking the shop for the season.
