FAQ

Can I inject SILCA Ultimate Tubeless Sealant 2.0 through the valve?

Yes. SILCA Ultimate Tubeless Sealant 2.0 is the injectable formula, designed to pass cleanly through the valve with the SILCA Ultimate Sealant Injector (sold separately). Remove the valve core, inject, then reinstall the core. Do not use the Replenisher Injector, which is for the FiberFoam sealant.

How is the 2.0 different from SILCA FiberFoam sealant?

SILCA Ultimate Tubeless Sealant 2.0 is the injectable latex formula that seals 6mm and larger punctures. The FiberFoam sealant uses carbon fiber strands to seal up to 7.5mm but must be poured in during install and is not injectable. They are separate products with separate injectors.

Does SILCA Ultimate Tubeless Sealant 2.0 work in cold weather?

Yes. SILCA Ultimate Tubeless Sealant 2.0 is tested to keep sealing down to -15C (5F), so it stays effective through cold-weather riding that can thicken or freeze other sealants.

Best For

Road, gravel, and MTB riders who want an injectable latex sealant that tops up through the valve, seals larger punctures, and keeps working in cold temperatures where other sealants struggle.
