LF Flat Copper Gasket ø22x17x2 mm

A flat copper gasket creates a tight, heat-resistant seal between the group head and portafilter of a commercial espresso machine. Copper conducts heat evenly and deforms slightly under pressure, filling microscopic gaps that would otherwise leak water or steam. This ensures the correct brewing pressure is maintained throughout extraction, preventing under-extraction or bitter over-extraction.

To replace the gasket, the operator first removes the old one by prying it out with a flat tool. The new gasket is positioned in the groove of the group head, ensuring it lies flat and centred. The portafilter is then reattached and tightened, compressing the gasket to form a secure seal. Over time, the gasket will wear and require replacement to keep the seal effective.

The gasket is made of copper, a material chosen for its malleability and thermal conductivity. Its dimensions—22 mm outer diameter, 17 mm inner diameter and 2 mm thickness—match the group head specifications of the listed machines, allowing it to fit precisely without distortion.

This gasket fits the following professional espresso machines: FIAMMA RST PRESTIGE; FRACINO BAMBINO, CHERUB, CONTEMPO, HEAVENLY and RETRO; VIBIEMME EVOLUTION, KOMETA, MINIMAX, REVOLUTION and SILVER. Regular replacement maintains consistent brewing pressure and extends the life of the group head assembly.

Cleaning is minimal: wipe the gasket with a damp cloth to remove coffee residue after each use. Avoid abrasives or solvents, as these can damage the copper surface and reduce its sealing ability.

This is a direct replacement part for the specified espresso machines, listed in the catering equipment catalogue under spare parts for coffee machines.
