The factory replacement for SILCA Press on Disc Chucks. The 252 replace the classic SILCA 25.1 gasket after more than 20 years in the market. This unique gasket borrows from industries which require air-tight seals in the harshest of environments. The 252 gasket utilizes a high tech, full synthetic elastomer base material. It tests to a life expectancy of more than 5X the carbon filled rubber or Buna-N materials used previously. In tests with a major disc wheel manufacturer, the current SILCA Disc Wheel Adapter with 252 gasket excelled by posting a blow-off pressure of 393psi where other designs were unable to reach 120psi. Older versions of the SILCA Disc Wheel Adapter will still benefit for the new gasket, but have a lower hands-free max pressure.

Replacement gasket for the SILCA HIRO Chuck

Years ago while Josh was working with the Team CSC at the Dauphine Libere, he noticed one of their mechanics using the most amazing little chuck to manage the disc wheel inflation. Unlike anything he had seen before, it was all metal and used a 'lollipop' lever on the side to lock onto the valve stems in disc wheels. The mechanic explained that these were made in Japan and were coveted by all the Euro-Pro mechanics due to their scarcity. So Josh set out to improve the design and make it available to cyclists everywhere. - Full metal construction, guaranteed for 25 years and covered by SILCAShield - Can effectively seal on valve stems as short as 10mm! - Uses SILCA 254 High-Tech Elastomer gasket - Adjustable gasket pre-load allows for a custom fit on any valve as well as compensation for gasket wear - Male Schrader thread fits into any Schrader chuck, or use SILCA Thread-On Schrader Adapter to fit a bare hose - Bullet-proof high-pressure, disc-compatible chuck for high-pressure situations.
