Meet Barkeeper

A Hi-Tec fiber, synthetic latex, tubeless sealant. The unique formula clings to the inside of the tyre and rim and therefore seals holes quicker than any other sealant.

Why Barkeeper?

Barkeeper lasts longer than other sealants, it does not ball up or dry out. It can be topped up without removing the old sealant. 

It is engineered for use on- and off-road, with pressures between 1 and 8 bar. Barkeeper works between -20°C to +50°C and is compatible with CO₂ cartridges. 

The use of Hi-tec fibers in the sealant, ensures larger punctures are sealed fast and permanently.

The formula is ammonia free, hypoallergenic, skin safe and non-corrosive.
