Bring a worn HIRO V2 chuck back to a clean, air-tight seal. The SILCA 254 is the bright red replacement gasket made for the HIRO V2 locking lever Presta chuck.

Built to outlast rubber

SILCA borrowed the material from industries that need air-tight seals in harsh conditions. In SILCA's testing it lasts more than five times as long as the carbon-filled rubber or Buna-N gaskets used previously.

Made for the HIRO V2 lever

The 254 has a large compression range to suit the HIRO V2 locking lever design. It slips easily over most valve stems, then the lever clamps it down to form a tight seal.

Compatibility & fit

Fits the SILCA HIRO V2 locking lever Presta chuck. For the original HIRO (V1) chuck, choose the SILCA 253 gasket.

SILCA covers rubber, leather and gauge-related parts under its Limited Warranty: free from manufacturer defects for two years from purchase. Normal wear is not a defect. For warranty support, return the product to Tune Cycles and we'll manage the claim with SILCA's Australian distributor.
