حلقة زنبرك P2011 8,0 | ECM ECM-P2011

My old seal was getting loose, but this 8mm ring locked everything back into place without any fuss. It’s exactly the right size and feels identical to the original piece.

It’s a snug fit that seated perfectly on the first try, so no wrestling with the group head assembly. The seal is noticeably firmer than the old one, which made a difference on the first shot’s pressure feel.

The 8.0 mm measurement was exactly what I needed to replace the old one in my machine. It fit snugly without any fuss, though I wish it came with a small diagram for installation. Still, the seal feels solid and my espresso is back to normal pressure.
