Prestaflator Big Presta Head Gasket – Quick Click, Replacement Grommet for All Prestaflator Big Push/Pull Heads & Silca 24.1/24.2 – 1 Gasket Included

I had not been able to use the nozzle because of how terrible the “gummy” one was that it came with. It doesn’t seal. It blows out the valve. I found this hard black one and it is a game changer. It actually works like it should. It deals on the valve. And it forms a tight seal. You have to hold it in place, but you already know that if you are using this nozzle.

Despite the description and pictures be aware that you are buying one grommet, not two as illustrated.It works. Silca chucks are the best.
