Caffewerks 矽膠沖煮頭墊圈 - 74 x 58 x 8.4mm Rancilio

It’s a huge improvement over the crusty old rubber one I pulled out—the silicone is noticeably more flexible and seats the portafilter way easier now. The seal feels consistent every time I lock it in, and I’m hoping this lasts much longer than the last gasket did.

Swapped my old rubber gasket for this silicone one, and the difference in flexibility is immediate. The 8.4mm thickness creates a noticeably firmer, more consistent seal with my portafilter.

I was worried about getting a good seal with my Rancilio, but this silicone gasket fits perfectly and locks in place with zero leaks. The flexibility makes it way easier to install than the old rubber one I struggled with.
