Muc-Off Inner Tube Sealant

Laugh in the face of flat tyres and keep your momentum going with an advanced inner tube sealant engineered to stop punctures in their tracks. The Muc-Off No Puncture Hassle Inner Tube Sealant is a super lightweight yet exceptionally powerful solution that automatically seals holes in tubes up to 4mm wide as you ride. Containing cutting-edge micro-molecules, this proprietary formula seals multiple punctures instantly and effectively so your journey remains uninterrupted. Compatible with a vast range of setups—including MTB, road, e-bike, commuter, urban, folding, touring, and TPU inner tubes—it provides reliable protection whether you are navigating urban glass, thorn-lined trails, or remote bikepacking routes.

Advanced Eco-Friendly Formula for Long-Lasting Protection

Designed specifically for inner tube applications, this water-based, non-hazardous sealant is completely free from harmful ammonia and chemically safe for your components. Integrated corrosion inhibitors guard your valves and rims against internal damage, while the water-soluble nature makes any accidental cleanup simple and stress-free. Unlike other sealants that dry out after a few months, this advanced mixture lasts for the entire lifespan of your inner tube without needing regular top-ups. Furthermore, it operates continuously across extreme temperature ranges from -15°C to +50°C, delivering consistent performance through freezing winter commutes and hot summer endurance rides.

Effortless Installation for Stress-Free Cycling

Installing puncture protection has never been easier thanks to a straightforward application process designed for inner tubes fitted with Schrader valves or Presta valves featuring removable cores. Simply inject the sealant into your tube to establish an invisible, lightweight shield that works silently behind the scenes. Ideal for everyday commuters, touring adventurers, and off-road trail riders seeking absolute peace of mind, this bottle eliminates the hassle of roadside tube swaps.
