حشوة مجموعة السيليكون من Caffewerks - 74 × 58 × 8.4 مم رانسيلو

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.

Finally, a gasket that actually stays soft and pliable instead of getting rock hard after a few weeks. The silicone is noticeably more flexible than the old rubber one I was using, and it seals my portafilter perfectly the first time every time.
