The SILCA 323 chuck gasket is a modern replacement for various SILCA brass chucks and the IMPERO frame pump. It features a high-tech synthetic elastomer, providing better valve holding power and sealing. This gasket ensures significantly improved life expectancy for compatible pumps. It revitalizes classic SILCA pumps for continued reliable performance.

This gasket incorporates a new 2-stage seal design, enhancing high-pressure performance. It also simplifies pump use by not requiring the chuck to be pressed as far as original designs. The material offers five times the durability of traditional rubber. It supports both Presta and Schrader valves when used with brass chucks.
