“We love these for our Nuova Simonelli's. We always keep the portafilters in the group-head at the end of the day, but not too tight. We believe that this keeps the rubbers more flexible for longer, and not dried out.”
“I bought this for my Musica and it fits perfectly. I had to dig my old one out in chunks and I ordered a ton of these from Espresso parts so I can replace them a little more regularly. These arrived in about two days and Saved my ass. Thank you!”
