This unique bright red seal is inspired by industries that require airtight seals in the harshest environments. It has been tested to last more than 5 times longer than previously used carbon-filled rubber or Buna-N materials. The Silca 254 gasket has a wide compression range to make the most of the PRESTA HIRO v2 locking lever chuck design. Easily fits over most valve stems, then secures the clamps to form a tight seal.
Designed for the cyclist or mechanic looking to restore their PRESTA SILCA HIRO v.2 LOCKING MANDRINK to like-new condition by replacing the gasket that creates the solid seal they expect.
