Silca 242 Gasket for Presta Chucks
The Iconic SILCA 24.1 gasket has been updated and improved after more than 30 years in the market, with the Silca Elastomer Presta Chuck #242. 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!

  • Fully Synthetic Elastomer Base Material
  • 5X the durability of traditional rubber materials
  • New Two-Stage sealing geometry optimized for all Presta valve stems
  • Pressure amplifying dome geometry uses air pressure to clamp valve stem
  • This gasket only works with 30.0/30.2 and 17-4 Stainless Presta heads on(more...)
