Nuova Simonelli 2280004 O-ring Swivel Steam Pipe

Product Description

The NUOVA SIMONELLI 2280004 is a genuine OEM replacement O-ring designed for the swivel steam pipe assembly on commercial espresso machines. This small-diameter elastomer seal sits at the swivel joint of the steam wand pipe, maintaining a leak-free connection under repeated thermal cycling and steam pressure. Proper sealing at this joint prevents steam bypass, protects adjacent components, and keeps the machine operating at rated performance. Certified technicians and commercial kitchen equipment service professionals install this part during routine steam wand maintenance or when inspecting for steam leaks at the group or wand assembly.

This O-ring is intended for use in commercial espresso and coffee equipment where swivel steam pipe assemblies are present. The input data confirms fitment with the Athena S, Aurelia II 4 Group, and Appia Compact model lines. It is a direct OEM replacement that maintains the original dimensional tolerances and material properties required for reliable steam-side sealing in high-cycle foodservice environments.

Installation Notes

Installation should be performed by a qualified commercial espresso equipment technician. Before servicing, shut off steam pressure and allow the boiler and steam circuit to fully depressurize and cool. Remove the old O-ring carefully to avoid scoring the sealing surface, and inspect the swivel fitting for wear or corrosion before seating the new seal. Apply a food-safe lubricant compatible with steam-side elastomers if required by the service manual for the specific model.
