Since Moser's hour record of 1984, SILCA has set the standard in adapting your pump head to work with the world's fastest wheels.  This latest version is 100% US manufactured in 6066-T6 aluminum and uses our new high-tech 252 Elastomeric internal gasket.  This 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% by simply tightening the cap.  In tests with a major disc wheel manufacturer, the new 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.
