This unique bright red gasket borrows from industries which require air-tight seals in the harshest of environments. It tests to a life expectancy of more than 5X the carbon filled rubber or Buna-N materials used previously. The SILCA 254 Gasket has a large range of compression to make the most of the HIRO v2 LOCKING LEVER PRESTA CHUCK design. Easily fits over most valve stems and then secure clamps to form a tight seal.
