La Marzocco GS Cage Style Flange Gasket

La Marzocco GS Cage-Style Steam Flange Gasket

A steam flange gasket for La Marzocco's older "cage" style boiler groups, the version with removable boiler nuts and studs, not the later welded-stud design.

SPECIFICATIONS

• ≈4.25" wide x 3.73" long, 2.25" x 2.09" ISD
• 8 bolt holes, 0.31" diameter
• 3/32" thick, compressed sheet, aramid fiber with nitrile binder
• Rated for steam to 750°F (399°C)
• Made in the USA

COMPATIBILITY

• Fits: La Marzocco "cage" style boiler groups with removable boiler nuts and studs
• Does not fit: welded-stud boilers, for that version use MZ_255

INSTALLATION

DIY-friendly gasket swap during a boiler flange reseal.

PRO TIPS

• La Marzocco recommends Loctite #68035 on this gasket, don't skip it, a dry-fit is far more likely to weep steam at the flange seam.
• Before ordering, confirm whether your boiler uses removable nuts/studs (cage style) or welded studs, this gasket only fits the cage style; installing it on a welded-stud boiler won't seal properly.
