Magic Milk Innertube Original Sealant - 250 ml

Puncture prevention for everyday bikes — commuters, folders, tourers, urban bikes, e-bikes. Water-based, lasts the life of the tube, seals holes up to 4 mm.

For riders who just want to stop getting flats. Innertube Original goes into your tube — commuter bike, tourer, e-bike, kids' bike — and gets on with it. It seals punctures up to 4 mm and lasts the life of the tube. You won't notice it until you need it. That's the point.

When a puncture opens, the sealant flows to the breach and seals it from the inside under pressure. The seal is durable — it doesn't need heat, CO2, or a second application. It holds at the pressures commuters, tourers, and e-bike riders actually run, from 30 to 80 psi.
