Caffewerks siliconen groepsafdichting - 71 x 56 x 9 mm

The silicone’s flexibility really shows when I swap gaskets—it seats perfectly without any wrestling, and the seal holds tight every single time. After a few months of daily pulls, it still feels as soft and consistent as the day I installed it, which is more than I can say for the rubber ones I use

Finally found a gasket that doesn't make me fight to lock in my portafilter—this silicone one is noticeably softer and seals perfectly every time. I've been using it for a week now and the consistency is exactly what I was hoping for.

It's noticeably easier to lock the portafilter into place than with the old rubber one, and the seal feels snug without any leaks. The only reason I'm not giving five stars is that it was a tiny bit stiff for the first day or two.
