The Iconic SILCA 24.1 gasket has been updated and improved after more than 30 years in the market. The new 242 gasket utilizes a high tech and very red, fully synthetic elastomer base material rather than a carbon black filled natural rubber of previous gaskets. 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 used previously. New Two-Stage seal geometry seals on both valve stem and at the base of valve core threads resulting in a more positive seal and improved durability. The new gasket slips onto the valve stem with a satisfying 'click', while unique internal geometry actually utilizes line air pressure to compress the gasket onto the valve stem: the higher you pump, the harder it grips the stem!
This design is so iconic we've found more than 20 companies world-wide making pump heads and gaskets copied from this, but none of them can come close to the precision and technology in our new 242.

- 5X the durability of traditional rubber materials
- New Two-Stage sealing geometry optimized for all Presta valve stems

Silca elastomer seal
by Kenneth C. of Palmetto, FL on July 12, 2020
Ownership: two months
Tech Knowledge: somewhat high
Pros
Product fits old style silca pump head. Old style black rubber seal no longer available. Seals connection of pump head to presta fitting with no leaks. Allows inflation of tire/tube to maximum pressure. Renewed pump and allowed me to keep using instead of replacing.
Cons
A little tricky to get used to at first, almost forms a click/like connection to presta fitting.
Other Thoughts
Glad someone finally made a replacement part for Silca pump head!
