La Marzocco OEM 7/9mm Conical Group Head Gasket

The thickest of La Marzocco's beveled conical group gaskets, for older machines with extensive wear on the groups and portafilters.

SPECIFICATIONS

La Marzocco old part #: L105/B9 (from Fa.G.I.); new part #: H.3.002 (from Ten-Fluid)
"7" = thickness at the outer diameter (flat portion); "9" = thickness at the inner diameter (peak of the cone)

COMPATIBILITY

INSTALLATION

Simple DIY replacement, no special tools required.

PRO TIPS

Install with the cone's sloped side facing down; the beveled edge gives the portafilter basket its sealing surface. If your portafilter has started locking noticeably past its normal position, this thicker 7/9mm gasket is the one to reach for over the standard 6/8mm version.
