The Muc-Off No Puncture Hassle Sealant 140 ml is a high-performance tubeless tire sealant designed to keep you rolling through flats, thorn punctures, and everyday trail debris without stopping your ride. Formulated with fast-acting sealing agents and stable liquid carriers, this sealant spreads quickly across the inside of your tire as you ride — instantly plugging holes small and medium-sized as they occur. Whether you’re hitting rough gravel, root-strewn singletrack, or city streets littered with glass, this trusted sealant helps ensure smoother, uninterrupted rides.

Engineered for both mountain and gravel tubeless setups, the No Puncture Hassle formula combines durable sealing particles with a low-viscosity base that flows rapidly into cuts and breaches in the tire casing. It forms a flexible, long-lasting seal that withstands rotation forces, temperature swings, and continued abuse from rough surfaces. The 140 ml bottle size makes it especially convenient for compact repair kits, pre-ride top-ups, or as a travel spare when you’re heading out for longer adventures away from home.

Adding or topping up sealant is simple — just remove the valve core or use a tubeless-ready rim’s access point, pour the recommended amount, and reinstall. As you ride, the sealant continually coats the inner casing, providing ongoing protection and maximizing puncture resistance. For riders who value peace of mind and fewer roadside stops, the Muc-Off No Puncture Hassle Sealant 140 ml is an essential component of any tubeless setup.
