Silcas attention to detail and constant improvement is what keeps their pumps operating for a lifetime. The 242 Gasket for Presta Chucks uses a fully-synthetic elastomer base material that increases the life expectancy five times over previous materials. Two-stage seal geometry seals on both valve stem and at the base of the core threads for a better seal and improved durability.
