The factory replacement for SILCA Press on Disc Chucks. The 252 replace the classic SILCA 25.1 gasket after more than 20 years in the market. This unique gasket borrows from industries which require air-tight seals in the harshest of environments. The 252 gasket utilizes a high tech, full synthetic elastomer base material. It tests to a life expectancy of more than 5X the carbon filled rubber or Buna-N materials used previously. In tests with a major disc wheel manufacturer, the current SILCA Disc Wheel Adapter with 252 gasket excelled by posting a blow-off pressure of 393psi where other designs were unable to reach 120psi. Older versions of the SILCA Disc Wheel Adapter will still benefit for the new gasket, but have a lower hands-free max pressure.

The Iconic SILCA 24.1 gasket is the heart of the press-on Presta chuck. The current 242 gasket utilizes a high tech and very red, fully synthetic elastomer base material.

The heart and soul of SILCA. The 731 washer is the same washer used in all Pista pumps for 60 plus years, and is crafted from the same leather as Italian handbags and sports car interiors. From a purely functional standpoint, inexpensive o-rings are most commonly used in this application, but no o-ring can match the smooth feel and zero-stiction action of a leather gasket. It is common today to find SILCA leather gasket pumps throughout the professional peloton (especially during the spring classics) as o-ring seal pumps struggle with heat and often are unable to seal once the pump barrel is hot from inflating more than a few wheels.

The unique bright red gasket borrows from industries that 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 - Easily replaceable gasket
