Caffewerks 矽膠沖煮頭墊圈 - 73 x 57 x 8mm

This gasket’s 8mm thickness creates a much tighter seal than my old one—no more leaks during extraction. The silicone is noticeably softer and easier to clean than the rubber version I used before. Definitely a solid upgrade for daily use.

Swapped out the old rubber one and the difference in feel is immediate — this silicone version locks in with a softer, more forgiving seal. It's held up through dozens of shots without hardening or losing its flexibility, which is exactly what I was hoping for.

The silicone feels noticeably more flexible than the rubber gasket I used before, and it seats into the group head without any wrestling. Seal is consistent when I lock in the portafilter, though I’m curious how the color holds up over a few months of daily pulls.
