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.

Replacement gasket for the SILCA HIRO Chuck

Replacement gasket for reversible brass chucks, modern Impero Frame Pumps, and Pocket Impero

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

This chuck comes from the same vendor who supplied them to SILCA pumps for more than 25 years. It makes a great replacement or addition if you are buying a new Stainless Presta chuck or CP1 Disc Adapter for your older pump. This part is made from nickel-plated brass and uses an o-ring to seal the connection. - Hose barb fits into all SILCA hoses both old and new - Threads onto Schrader valves and all SILCA chucks with male Schrader threads (17-4 Presta chuck, HIRO, and CP1 Disc Adapter) - All metal construction, nickel-plated brass
