Super lightweight tubeless sealant with Hi-Tec fibers.

Dynamic Barkeeper is a tubeless synthetic latex sealant with Hi-Tec fibers. Its unique formula adheres to the inside of the tire and rim, sealing holes faster than any other sealant. Barkeeper lasts longer than other sealants, does not clump or dry out. It can be refilled without removing the old sealant.

It is designed for on-road and off-road use, with pressures between 1 and 8 bar. Barkeeper operates between -20°C and +50°C and is compatible with CO₂ cartridges. The use of Hi-Tec fibers in the sealant ensures that larger perforations are sealed quickly and permanently. The formula is ammonia-free, hypoallergenic, safe for the skin and non-corrosive.
