Details
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 slip 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, Silca have 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 the new 242.

- Fully synthetic elastomer base material
- 5 Times 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
- Fits all prior Silca presta heads
- Made in USA

This gasket only works with 30.0 / 30.2 and 17-4 Stainless Presta only chucks.
