La Marzocco After-market 7/9 mm Conical Group Head Gasket

This gasket fits La Marzocco GS-2, GS-3, Linea, FB-70, GB-5 and FB-80. The thickest version with a bevel, used on older machines with extensive wear on the groups and portafilters. The "7" refers to the thickness on the outside diameter, the flat portion, and "9" refers to the thickness on the inside diameter, up to the peak of the cone shape. Installed correctly, with the cone sloped side facing down, the beveled edge of the cone shape adds an additional surface for a portafilter basket to seal against. This is a suitable replacement for La Marzocco old part #: L105/B9, new part #: H.3.002.
