Silca 252 Rubber Washer Elastomer Replacement Seal Aluminum Presta Disc Chuck

The SILCA 252 gasket is a replacement constructed from an innovative fully synthetic elastomer that supplies 5x the life expectancy of classic rubber seals. The design seals tightly against the valve to keep an air tight lock, preventing blow offs at high pressure. This seal is backwards compatible with previous Silca disc adaptor design.
