Back in production, having been unavailable for many years, this
is a new and improved version of the classic 323 gasket.
"Finally! The 'missing' SILCA gasket is back in production.
There are at least 3 original brass chucks that use this gasket 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 gaskets 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 gasket has been developed using the same
high-tech fully synthetic elastomer used on our modern 242 gasket
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 gasket your classic SILCA pump
will literally perform BETTER than new!"
