SILCA Ultimate Tubeless Valves - Pair, 50/70 mm

A tubeless valve is a small part until air or sealant stops flowing through it properly. SILCA Ultimate Tubeless Valves focus on that exact point: high airflow, compatibility with most tyre inserts and a serviceable design that does not require a separate tool for every job.

The valve body is precision CNC-machined from aluminium. Channels at the base leave a path for air and sealant even when an insert sits inside the tyre. The removable Presta core makes sealant injection easier and the threaded aluminium cap doubles as a valve-core tool.

Each pack contains one pair of black valves.

Choose 50 mm or 70 mm

50 mm is SILCA's recommendation for rims less than 40 mm deep. This version is threaded along the full stem.

70 mm is designed for rims 40-60 mm deep. The longer stem leaves enough room for a pump head on a deeper rim.

A 4 mm hex interface at the base gives controlled installation. Final tightening is hand tight. The low-profile lock nut sits neatly against the rim.

Why does a removable core matter?

With the core removed, sealant can be injected through the valve and the larger opening provides more airflow when seating the tyre. The core is also easy to clean or replace if dried sealant begins to restrict flow.

Frequently asked questions

Are the valves sold individually or as a pair?
Each pack contains two valves.

Which length should I choose?
Choose 50 mm for rims under 40 mm deep. Choose 70 mm for rims 40-60 mm deep.

Do they work with tyre inserts?
SILCA states that the design works with most tyre inserts. Channels around the base help prevent an insert from blocking airflow.

Can sealant be injected through the valve?
Yes. The valves have removable cores and are designed for injectable sealants.
