An ultra-compact disc chuck adapter designed to access Presta valves in the tightest spaces. The unique bright red gasket borrows from industries which require air-tight seals in the harshest of environments and tests to a life expectancy of more than 5X the carbon filled rubber or Buna-N materials.  The 252 gasket mates with a new compression head design allowing the user to tighten the gasket fit by nearly 200% with a simple twist of the cap.  In tests with a major disc wheel manufacturer, the SILCA Disc Adapter literally blew away the field by posting a blow-off pressure of 393 psi, more than 3X the pressure achieved by any competing design. 


  • CNC’d 6061 aluminum alloy construction.
  • Knurled gripping surfaces.
  • Threads into any Schrader pump head.
