Give a classic SILCA brass chuck or Impero head a seal that works better than the original. The 323 was redesigned from scratch using SILCA's modern synthetic elastomer.

Highlights

  • Same synthetic elastomer as the 242 gasket on the SuperPista Ultimate
  • More valve holding power and better sealing
  • Two-stage seal improves high-pressure performance
  • No need to press the chuck on as far as the original design

Why it was redesigned

SILCA couldn't find unused original 323 gaskets to benchmark, so the team rebuilt the part around the fully synthetic elastomer used in its modern 242 gasket. SILCA says it gives greater valve holding power, better sealing and much longer life than the original.

Compatibility & fit

Fits at least three original SILCA brass chucks (including the reversible brass chuck) and the SILCA Impero frame pump head.
