LF Copper Flat Gasket for Professional Coffee Machines & Bratt Pans

A copper flat gasket creates a pressure-tight seal between the portafilter and the group head of a commercial coffee machine. The metal ring sits in a groove around the group head and deforms slightly when the portafilter is locked in place, preventing water and steam from escaping during extraction. The same principle applies to bratt pans, where the gasket seals the lid or inspection hatch against the rim of the pan, stopping steam and cooking liquids from leaking under pressure.

To use the gasket, the operator first removes the old one from its groove. The new gasket is pressed into the groove by hand, ensuring it lies flat and evenly all the way round. Once seated, the portafilter or lid is reattached and tightened; the gasket compresses and fills any microscopic gaps, restoring the seal. Over time, the copper work-hardens and loses elasticity, so the gasket is replaced as part of routine maintenance to keep the machine operating at full pressure.

The gasket is a flat ring of copper, 1.5 mm thick, with an outer diameter of 19 mm and an inner diameter of 13.5 mm. Copper is chosen for its malleability and resistance to the heat and moisture inside the group head or bratt pan. The dimensions match the groove in the specified models, so the gasket fits without stretching or bunching.

The 1.5 mm thickness allows the gasket to deform under the locking force of the portafilter or lid, creating a reliable seal without requiring excessive torque. The 19 mm outer diameter ensures the gasket sits securely in the groove, while the 13.5 mm inner diameter leaves the water pathway unobstructed.

Cleaning is limited to wiping the gasket with a damp cloth before installation to remove any dust or grease. Once fitted, the gasket is not cleaned separately; it is replaced when the seal begins to leak or the copper shows signs of fatigue.

This gasket fits a range of professional coffee machines and bratt pans: Futurmat-Ariete (Ariete, Custom, E61, F3, Palanca, Rimini), Gaggia Spagna (Bella, Nera, Palanca), Italcrem (Capri, Palanca), Mairali (Arianne, Giulietta, Palanca), Sanremo (Amalfi, Capri, Milano LX, Pisa, Torino, Treviso, Treviso LX, Venezia, Verona, Zoe), Visacrem (Brava, Nera, Palanca), and Zanussi electric and gas bratt pans (BR80EZ, BR180Z, BR100Z, BR100E, BR180E, BR80E, BRG/350, BRG350Z, BR80GZ, BRG180Z, BR100GZ, BR100G, BR80G, BRG/180).
