About this item

  • Upgraded | The new 242 gasket utilizes a high-tech, fully synthetic elastomer base material rather than a carbon black filled natural rubber of previous gaskets.
  • Long-Lasting | Silca Elastomer Seal Presta Air Chuck 242’s life expectancy is 5 times more than traditional rubber gaskets like carbon-filled rubber or Buna-N materials.
  • Reinvigorate Your Pump | The option of buying a gasket part saves you time and money! Instead of investing in a new pump, get a new seal to make your Silca pump last a lifetime!
  • Efficient Seal | This elastomer seal is easier to get on and off the valve stem, No more leaking air problems with this improved Silca Elastomer Seal Presta Chuck 242. Great to keep on your Silca bag/emergency kit.
  • Versatile | The new two-stage sealing geometry is optimized for any Presta silca valve stem. Works well with Silca floor and hand pumps/inflators like a Silca Superpista pump.

I love Silca products. But it seems odd that you would rate a replacement part for a pump. Mine was worn out and this is the replacement. It works - until it doesn’t.

Ricambio ottimo: calza perfettamente la campana delle vecchie pompe Silca (la mia ha più di vent'anni) e ne ripristina la funzionalità.C'è anche scritto che durare almeno 5 volte la vecchia versione nera, vedremo: per adesso sono MOOOOLTO soddisfatto!

It works fine especially for smooth sided valve stems. Much longer lasting than the original black ones.

3日に一回程度の使用頻度で、前回の購入からカウントして4年と一ヶ月使用可能だった。ゴム製であることを考慮すれば耐久性は満足てきるレベルだと考える。交換直前の数回は空気が抜けるのが分かるため、変え時であることが分かる。

More resilient than the old black rubber seal. New life for my old Silca head.

We’ll see if it lasts longer than the rubber ones. Restored my Silicas operation.
