Orm gasket LF L1486015

An orm gasket creates a pressure-tight seal between the portafilter and the group head of an espresso machine. The ring sits around the rim of the portafilter basket, pressing against the machine's metal surface when the handle is locked. This prevents hot water from escaping under pressure, ensuring the water flows through the coffee grounds at the correct force to extract flavour and crema.

To use the gasket, the operator removes the old ring from the portafilter or group head groove, cleans the channel, and presses the new silicone ring into place. The red silicone is flexible enough to seat evenly without twisting, yet firm enough to resist deformation when the portafilter is tightened. Once fitted, the machine can be reassembled and tested with a blank shot to confirm no leaks occur during extraction.

The gasket is made of red silicone, chosen for its resistance to heat and compression set. The material remains stable across repeated heating and cooling cycles, maintaining its shape and sealing properties over time. A thickness of 4.1 mm and an internal diameter of 35 mm match the groove dimensions of the specified espresso machines, ensuring a precise fit without gaps or overhang.

This gasket fits espresso machines manufactured by DE LONGHI and EPMS, including models referenced by part number 5332149100.
