This 48mm group screen fits most La San Marco Espresso machines.
If your spray pattern coming from your group head is spraying all over, if your flow is reduced because the screen is clogged, or if your coffee tastes funny because you just can't get your screen clean, replace it and start fresh!
While replacing your group screen it's a good idea to replace your group gasket at the same time. Most San Marco machines in the US use a 6mm gasket found here.
If you're unsure if that's the correct gasket please contact our service department and they'll be able to help you out. They can be reached via email at email@example.com
