Silicone O-ring LF L10027147

An orm-ring creates a watertight seal between the brew group and the boiler in superautomatic coffee machines. The ring sits in a groove and is compressed when the machine closes, preventing water from leaking past the joint. Silicone is used because it remains flexible at the temperatures and pressures of espresso brewing, does not absorb coffee oils, and resists hardening over repeated heating and cooling cycles.

The operator does not interact with the ring directly; it is installed inside the machine during assembly or repair. Once fitted, the ring requires no adjustment or maintenance beyond the routine cleaning of the brew group. The machine closes and opens automatically for each shot, so the ring is repeatedly compressed and released without user intervention.

This orm-ring is made of food-grade silicone. It fits the specified models of Gaggia and Accademia superautomatic coffee machines, including the Anima, Babila, Brera and Naviglio ranges. The part is listed under spare components for espresso equipment.
