Nutrak Magic Milk tubeless tyre sealant is a latex-based liquid designed to prevent punctures in tubeless tires for road, gravel, and mountain bikes. It claims to seal holes up to 6mm and coat the sidewall effectively4.
Key features and considerations:
- Puncture Protection: Designed to offer maximum protection by sealing holes. Some users have reported it effectively seals smaller punctures, but may not seal larger slits34.
- Application: It is a free-flowing sealant that fills gaps between the tire bead and rim, which makes it easy to set up, even with rim inserts4.
- Formula: The sealant is designed not to separate or form lumps inside the tire, ensuring it remains effective as long as it is liquid4.
- Volume: Suitable for various tire sizes; 100ml is recommended for 26″, 27.5″, and 700c tires, while 120ml is best for 29″ tires5.
- Potential Issues: One user review suggests that the sealant can create an uneven surface that prevents tubeless tires from sealing, and can be difficult to remove once dried. This user had to replace their rims after using the product
