Magic Milk Innertube-Pro Hi-Fibre Sealant - 5 L

For MTB riders still running tubes, this is the formula that handles what tubes take the worst — snake bites, pinch flats, slits up to 7 mm. 

The same fibre technology that sealed AON Racing's tubeless tyres — rebuilt for riders who run tubes. Innertube-Pro Hi-Fibre handles snake bites, slits, and punctures up to 7 mm. It's CO2 compatible, works from −20°C to +50°C, and runs at the pressures DH and enduro riders actually use. The strongest innertube sealant in the Magic Milk line.

The fibre-reinforced formula works the same way it does in the tubeless version: when air escapes, fibres rush to the breach, pack the hole, and bind into a durable seal — not a temporary patch. It doesn't ball up inside your tube. It doesn't migrate and dry out under hard riding.

Features of Magic Milk Innertube-Pro Hi-Fibre Sealant:

• Max puncture sealed: 7 mm — including snake bites and slits
• Pressure range: 2–58,3 bar; 30–120 psi
• Temperature range: −20°C to +50°C
• Lasts as long as your tube or tyre.
• System: innertubes — Downhill, Enduro and MTB
• CO2 compatible
• Non-corrosive — safe for tubes and rims
• Water-based: lasts the life of the tube and tyre
• For use with removable-core Presta, and all Schrader, tube valves.

Why fibre-reinforced

Most innertube sealants are liquid patches — they fill a hole and hope the pressure doesn't push them out. The fibres in this formula cross-link under pressure, turning the seal from a plug into a bond. It's the difference between a tube that limps home and one that finishes the descent.
