The NUOVA SIMONELLI 2290016 is a red silicone O-ring used to seal connections between components in commercial espresso machines and related equipment. Silicone construction provides flexibility and resistance to heat and moisture, making it well-suited for the high-temperature environments typical of espresso brewing systems. At 0.3 inches in length, 0.3 inches in width, and 0.1 inches in height, this is a small but critical sealing component. It is sourced as a genuine OEM part, meaning it is manufactured to the same dimensional tolerances as the original. Licensed technicians and trained equipment service professionals handle installation during routine maintenance or leak repair procedures.
This O-ring is intended for use in commercial espresso and coffee equipment serviced in cafes, restaurants, and food service environments. Per the supplier data, compatible models include the Adonis 2 Group and Appia Compact. Consult the full model fitment list from NUOVA SIMONELLI to confirm compatibility with additional equipment before ordering. This type of sealing component is typically replaced during scheduled preventive maintenance or when a leak is detected at a component joint.

Installation should be performed by a qualified espresso equipment technician or trained service professional. Power down and fully depressurize the machine before removing any components or existing seals. Inspect the seating surface for debris or damage before installing the new O-ring. Do not use petroleum-based lubricants on silicone O-rings; use only food-safe, silicone-compatible lubricants where required.
