Silca Ultimate Tubeless Sealant with Injectable FiberFoam

Silca Ultimate Tubeless Sealant with Injectable FiberFoam is designed for cyclists who demand reliable puncture protection, excellent air retention, and long-lasting tubeless tyre performance. Developed with advanced FiberFoam technology, this premium sealant combines a foaming latex formula with recycled chopped carbon fibers to create an aggressive sealing solution capable of handling larger punctures. The carbon fibers are carried directly to the damaged area, helping seal cuts and holes quickly while minimizing pressure loss. Suitable for road, gravel, and mountain bike applications, it performs effectively across a wide range of riding conditions, including colder temperatures. With a long service life of up to 9 months and dependable sealing performance, this sealant helps reduce maintenance while keeping you riding with confidence on challenging terrain and long-distance adventures.

FiberFoam Sealing Technology

Silca's FiberFoam technology is engineered to improve puncture sealing efficiency by combining foaming latex with multiple lengths of recycled carbon fibers. As air escapes through a puncture, the fibers are drawn toward the damaged area where they create a reinforced structure that helps close larger holes. This unique system provides stronger and more durable sealing compared to many traditional tubeless sealants, making it ideal for riders who regularly encounter rough roads, gravel trails, and technical terrain.

Easy Operation / Usage

• Remove one side of the tyre during tubeless setup

• Pour the recommended amount of sealant directly into the tyre

• Reinstall the tyre and inflate to the desired pressure

• Rotate and shake the wheel to distribute sealant evenly

• Check sealant condition periodically and add replenisher every 90–120 days if required

• Add extra sealant for lightweight tyre casings that absorb or lose sealant more quickly
