The Silca Ultimate Tubeless Sealant 1 Litre is the go-to solution for serious riders and workshops who want maximum puncture protection with long-lasting performance. Built around Silca’s advanced fibre-foam technology, this premium formula uses carbon fibre strands and sealing crystals to create a fast, durable seal capable of repairing larger punctures than traditional latex sealants.

Designed for high-performance road, gravel and MTB applications, Silca Ultimate seals punctures up to 6mm while maintaining low rolling resistance and consistent air retention. The fibre matrix interlocks instantly when exposed to air, creating a reliable plug that keeps you rolling without drama.

The 1L bottle is perfect for multiple bikes, regular top-ups, team use or workshop installations — offering better value per application while delivering race-level reliability.

When you want fewer ride interruptions and more confidence at speed, this is the sealant that performs.
