Group Head Portafilter Gasket – 72 x 56 x 8 mm (Astoria New Style) This OEM-style portafilter gasket fits newer Astoria, Laurentis, and Rio espresso machines built after approximately 1995. It measures 72 x 56 x 8 mm with three internal cuts, and is the thinner of two available gaskets, best suited to new or moderately worn group heads and portafilters.
