What makes SILCA Ultimate Tubeless Valves worth using?

SILCA Ultimate Tubeless Valves are precision CNC-machined aluminum with a 4mm hex interface at the base for secure, tool-controlled installation, so you get a firm, airtight seat without guesswork. A conical rubber base washer improves the seal at the rim while protecting the rim finish from scuffing, and the design is compatible with most tire inserts, a common pain point where oversized insert foam interferes with standard valves. A large internal bore keeps airflow high for fast tire seating and easy sealant injection. The threaded aluminum valve cap doubles as a core tool, so you always have what you need to pull the valve core, and a low-profile lock nut keeps the valve flush and rattle-free.

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. Sold as a pair and backed by the SILCA Limited Warranty.
