La Marzocco OEM Silicone Conical Group Head Gasket

This was my first time changing gaskets out on my new KB90. The description says it is suitable for my machine, but it is not shaped correctly for the KB90 at all.

Installed this on my la marzocco classic. Easy to install and made a better seal on the portafilter. Remember to use food safe grease.

The hard part was getting the old gasket out. Once it was out the installation was straight forward. The silicon version seals better and requires only a light twist of the portafilter. It’s a huge improvement over the old rubber gasket.
