Overview
What makes the SILCA Ultimate Tubeless Sealant seal so well?
SILCA Ultimate Tubeless Sealant is the updated, injectable version of SILCA's tubeless sealant, reformulated so it stays liquid longer and injects cleanly through the valve, the two things riders asked SILCA to fix from the original. It uses a proprietary blend of natural and synthetic latex built to seal punctures 6mm and larger, and it is tested to keep sealing down to -15C (5F). It is ammonia free and runs as a one-step product.
It is injectable through the valve using the SILCA Ultimate Sealant Injector, sold separately, and is available in 65ml, 500ml, and 1L bottles. One compatibility note matters: SILCA says it is not injectable in Reserve valves. SILCA also recommends running it with a TPP rim tape.
