Astoria Lever Group Head Portafilter Gasket – 67 x 56 x 6mm This is the group head gasket for Astoria's Gloria lever group, and it also turns up in old pre-1993 solenoid-group Astoria machines built before the company switched to the modern group seal. If you're working on a true lever machine, this is your part. COMPATIBILITY Fits: Astoria Gloria lever group heads; also pre-1993 solenoid-group Astoria espresso machines Replaces: can be substituted with the AS_60 lever piston o-ring style gasket Works with: group head/portafilter seal interface INSTALLATION Simple swap for anyone comfortable removing and reseating a group gasket, no special tools needed. PRO TIPS This gasket is rarely the right answer on a modern machine, it's specifically for lever groups. If you don't have a lever group, you're almost certainly looking for the AS_56 instead, so double-check your group type before ordering.
