SILCA - 254 Gasket for Hiro V.2 Locking Presta Chuck

The SILCA 254 Gasket is the replacement seal for the HIRO v.2 Locking Presta Chuck — and it's a significant upgrade over the rubber materials it replaces. Made from a fully synthetic elastomer base, the 254 gasket tests to more than 5x the service life of the carbon-filled rubber and Buna-N materials previously used in this application. Its large compression range makes the most of the HIRO v.2 lever design, fitting cleanly over most valve stems before clamping to form a reliable air-tight seal.
