The seal is snug and holds firm during pulls, so I’m finally getting that consistent pressure without any drips sneaking around the basket. I’ve swapped it into my daily driver and it fits like a glove, no wobble or fuss.

My machine was dripping from the group head for weeks, so I swapped in this precision o-ring and the seal is now completely secure during the whole extraction. It fit perfectly without any fiddling, and the consistency of my shots is noticeably better.

The old gasket was leaking all over the counter, but this one seals the portafilter perfectly the moment I lock it in, so my shots run clean and even every time.
