Joint torique 03181 silicone rouge - Joint de groupe Profitec Go

The silicone feels noticeably more pliable than the stock rubber, which made seating it into the group head a breeze. Brewing pressure has held steady across a dozen shots since I swapped it out, and the bright red color is a nice visual cue when it’s time to inspect for wear.

Installed this on my Profitec Go and the silicone feels more pliable than the stock rubber gasket, making the portafilter lock in with less effort. No more leaking around the group head during extraction.

Swapped out the old group gasket for this silicone red one and it slid right into place on my machine. The silicone feels more pliable than the original rubber, so it seals up without needing to torque the portafilter too hard. No more minor leaks during backflushing, which is exactly what I needed.
