Description
FINALLY! The 'missing' SILCA seal is back in production. There are at least 3 original brass chucks that use this seal as well as the Impero frame pump. However, none of them were as widely sold as the Presta Only chuck and we had been unable to find original 323 seal that were unused and in near original condition to assess performance, so the team at SILCA had to completely redesign and optimize this part from scratch.
This modern 323 seal has been developed using the same high-tech fully synthetic elastomer used on our modern 242 seal on the SuperPista ultimate. We find that this material allows for greater valve holding power, greater sealing and significantly improved life expectancy. New 2-stage Seal Design improves high pressure performance and also makes it unnecessary to press the chuck on as far as the original design required. With a 323 seal your classic SILCA pump will literally perform BETTER than new!
This is the seal you need if you have any of the chucks shown in the images, they all share the feature of being reversible so that you can take out the seal and other inside pieces and flip them over to convert the chuck from presta to Schrader. We know of the 3 models shown in the photos, but amongst these there are at least 6 variants of the plastic pieces that go inside the chucks. We are not able to remake any of the plastic pieces from inside these chucks. If your plastic pieces are broken you can still use this seal to keep your chuck presta compatible but Schrader will not be an option.
Compatibility:
- Art.24.4, Art.84 & Art.323
- SILCA Impero frame pump heads
