@disq@mmccarthy Not the group head gasket (already found these in my google-ings) there is a seal where the spout of the portafilter screws on, wondered if this was a 'standard' size before i get my calipers out.
Googling "portafilter spout gasket" seems to give plenty results, short of finding an OEM replacement, surely a food/temp safe one that's the right size should be fine.
