Stan's NoTubes Original Tubeless Sealant, introduced by our founder Stan in 2001, remains a pioneering and trusted choice among riders for its exceptional puncture-sealing capabilities. This sealant is the first of its kind, specifically designed to meet the needs of all tubeless road, gravel, and mountain bike tires. It continues to be the preferred option for cyclists seeking reliable all-around performance.

The Original formula offers robust puncture sealing that effectively handles breaches up to 6.5mm (¼ inch) in diameter. It is engineered to stay liquid within the tire for a period of 2-7 months, providing durable protection against punctures. In arid conditions, however, it is advisable to check the liquid sealant levels more frequently to ensure continuous efficiency. Additionally, this sealant includes anti-freezing agents, which allow it to perform optimally in temperatures as low as -20ºF, making it suitable for a wide range of riding conditions.

Easy to use, the sealant can be administered directly through the tire valve using Stan’s Tubeless Sealant Injector, simplifying the maintenance process. Whether you're tackling rugged mountain trails, smooth road surfaces, or mixed gravel paths, Stan's NoTubes Original Tubeless Sealant provides the essential protection you need to ride with confidence.
