MaXalami MaXseal tubeless tyre sealant is specially formulated to work with high pressure (road tubeless) and very low pressures (MTB tubeless). It of course with moderate pressures (CX tubeless).
The 250ml bottle comes with its own applicator but for fitting to presta valves push the tube down to the collar please.
Holes up to 7mm can be sealed and the sealant can last up to 6 months.
The formulation uses a high concentration of fibres, is ammonia free and uses artificial latex so it won't ball up like natural latex sealants. There is no need to clean a tyre out with this sealant, just top up when you need to.
MaXSeal manufactured by a company specialising in sealants for military and commercial vehicle use.
