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 PRESTA’s HIRO v2 locking lever chuck design. Easily fits over most valve stems, then secures clamps to form a tight seal.
\nDesigned for the cyclist or mechanic looking to restore their PRESTA SILCA HIRO v.2 LOCKING LEVER MANDRIN to like-new condition by replacing the gasket that creates the solid seal they expect. <\/p>\n
Features:
\n– SILCA 254 gasket for PRESTA “HIRO” V.2 chuck
\n– Synthetic elastomer base material
\n– Durability 5 times greater than traditional rubber
\n– Compatible with HIRO v2
\n– 6 mm height x 15 mm outer diameter<\/p>\n","protected":false},"excerpt":{"rendered":"
