Parts covered by SILCA Limited Warranty are considered to be subject to wear through normal use or are consumable subject to degradation through the course of their daily use. SILCA guarantees them free from manufacturer defects for 2 years.
There are at least 3 original SILCA 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!

can't tell it from new/original
Chuck gasket; what's the big deal? This is a replacement gasket for my wife's 20 year old Silca pump. Meanwhile, I dropped $15 for a pump head replacement to replace the last one that didn't last a year. Thanks Silca for your great, serviceable, long lasting products and keeping plastic crap out of landfills.
SILCA products are ingeniously designed to be totally and easily serviceable. I’ve had many years of dependable use out of these purpose-driven tools; my first floor pump from the late 1980’s is rebuilt and still in service. Plus, it is handy to have their instructional videos on Utube.
Gotta love things that are built to last.
This gasket works great and lasts longer than the old black rubber one.
