With the Black Inc Tubeless Tire Sealant, a cycling life without flats is no longer too good to be true. Our latex free, natural sealant formula provides essential protection from all but the most severe tire punctures and slashes.

Capable of sealing instantly an 8mm puncture hole for a gravel or mountain bike tire, and 6mm for road tires, the Tubeless Tire Sealant ensures the tubeless tire adheres securely to the tubeless rim, while helping you to escape ride-ruining punctures. With a shelf life of up to 26-months, this Sealant provides reliable long-term protection, though we recommend you top-up your tires every 8 to 12 weeks, depending on your riding situations, environment, and temperature.
