Flat Fix XXL Tyre Sealant – Extreme Heavy-Duty Puncture Protection

The strongest tyre sealant for mining, construction, forestry, and heavy transport.

Flat Fix XXL tyre sealant prevents up to 95% of punctures and seals holes up to 30 mm instantly. Designed for extreme environments, it uses Kevlar-infused fibers and next-generation sealing technology to create a reinforced internal barrier.

Reliable performance from -40°C to +92°C ensures maximum protection all year round.
