The SILCA Ultimate Tubeless Valves offer high flow rates and easy compatibility with tire inserts. These valves provide reliable long-term service within a tubeless system. Their construction includes a precision CNC-machined aluminum body and a brass conical base for a secure rim seal. Length options are available to suit various rim depths.

The design features a dual O-ring sealing system, which isolates the valve core from sealant, preventing clogs. Precision brass valve cores ensure consistent seal pressure and smooth removal for sealant top-offs. A 4mm hex interface supports secure installation, while the aluminum cap doubles as a valve core tool for convenience. Knurled locknuts allow for tool-free installation.
