This flat, square profile portafilter gasket is for the brass sleeve machines, (also fits very early series La Pavoni EuroPiccola, and Cremina). If you have the type of machine that has a lower cylinder that screws out to address the piston, etc, then you likely have this flat portafilter gasket. Made from Hard Rubber. We also currently have this part in Silicone, but if you prefer rubber, this is the one for you! Limited supply...
