Keep your SILCA disc wheel adapter sealing like new. The 252 replaces the classic SILCA 25.1 gasket, which ran for more than 20 years.

Highlights

  • Full synthetic elastomer, more than 5x the durability of traditional rubber
  • Two-stage sealing geometry for all Presta valve stems
  • Fits all prior SILCA disc wheel adapters

Holds serious pressure

In testing with a major disc wheel manufacturer, the current SILCA Disc Wheel Adapter with a 252 gasket reached a blow-off pressure of 393 psi, where other designs couldn't reach 120 psi. Older adapters still benefit from the new gasket, but have a lower hands-free maximum pressure.

Compatibility & fit

Fits all SILCA disc wheel adapters, including earlier versions. Presta valves.

SILCA lists this gasket as covered under its Limited Warranty: free from manufacturer defects for two years from purchase. Normal wear is not a defect. For warranty support, return the product to Tune Cycles and we'll manage the claim with SILCA's Australian distributor.
