SILCA - 252 Gasket for Disc Adapter

The SILCA 252 Gasket is the replacement seal for all SILCA disc wheel adapters — and it outperforms the classic 25.1 gasket it replaces by a wide margin. A fully synthetic elastomer base material with a new two-stage sealing geometry tests to more than 5x the service life of the Buna-N rubber it supersedes. In head-to-head testing with a major disc wheel manufacturer, the current SILCA Disc Wheel Adapter equipped with the 252 gasket achieved a blow-off pressure of 393 PSI — a result competing designs couldn't approach.
