Overview
What makes SILCA Ultimate Tubeless Valves worth using?
SILCA Ultimate Tubeless Valves are precision CNC-machined aluminum with a 4mm hex interface for secure, tool-controlled installation. The design is compatible with most tire inserts. The threaded aluminum valve cap doubles as a core tool, so you always have what you need to pull the valve core, and the lock nut is low profile.
They come in 50mm and 70mm lengths to fit standard and deep-section rims, and are built to work as part of the SILCA tubeless system alongside SILCA Ultimate Tubeless Tape and SILCA Ultimate Tubeless Sealant. Backed by the SILCA Limited Warranty.

FAQ
Good questions
Get to know Silca

There's more to Silca than this one product. Our Silca page has the full Silca lineup we carry and more about the brand.
Visit the Silca page →What valve length do I need for deep-section rims?
SILCA says to choose the 50mm valve for a rim depth under 40mm, and the 70mm valve for a rim depth between 40 and 60mm. Measure your rim depth and confirm the valve extends far enough for your pump chuck to engage cleanly.
Do SILCA Ultimate valves work with tire inserts?
Yes. The SILCA Ultimate valves are designed to be compatible with most tire inserts.
How do I remove the valve core for sealant?
The threaded aluminum valve cap has a built-in core tool. Unthread the cap, use its core-tool end to remove the valve core, inject sealant with the SILCA Ultimate Sealant Injector, then reinstall the core and cap.
