Product details

No Puncture MTB Sealant Liquid Muc-Off: reliable tubeless protection for any terrain

The Muc-Off No Puncture tubeless sealant is an advanced solution for mountain biking, downhill, enduro, and road touring. Formulated with cutting-edge microfiber molecules, this 500 ml sealant effectively seals punctures and tears up to 6 mm in diameter, delivering reliable performance in the most demanding race conditions. Advanced latex technology creates an instant seal, while the exclusive UV detection system quickly identifies any punctures not visible to the naked eye while riding. Compatible with UST, tubeless ready, and full tires, the product maintains its effectiveness across a wide pressure range (15-120 psi) and temperature range (-20°C to +50°C).

Technical features and sealant durability

This sealant liquid formulation has been developed in collaboration with professional teams and riders from the world’s best downhill disciplines, ensuring high quality standards. The product also seals porous tires and gaps between the rim and tire, significantly reducing the risk of punctures while riding. Durability reaches 6+ months in temperate climates without swelling or degradation, maintaining consistent performance over time. The formula is biodegradable and non-corrosive, making it safe for aluminum and steel components. Ammonia-free and fully compatible with CO2 cartridges, the sealant washes off easily with water, simplifying wheel maintenance and cleaning.

Ease of use and compatibility with tubeless systems

The 500 ml pack includes a specially designed case that fits Presta valves perfectly, making it ideal for carrying in your tool kit or ride kit for emergency top-ups on the go. This tire sealant is a versatile choice for anyone using tubeless tires across different cycling disciplines, from mountain biking to touring. Universal compatibility with tubeless ready and full systems, combined with ease of application, makes it suitable for both experienced riders and average cyclists. Fast, reliable sealing technology reduces downtime in the event of a puncture, allowing you to keep riding with peace of mind even on technical and rough terrain.
