Product Description The NUOVA SIMONELLI 2280009 is an EPDM o-ring gasket designed for use in commercial espresso machines and related beverage equipment. EPDM (ethylene propylene diene monomer) rubber is well suited for high-temperature, steam, and hot-water sealing applications, making it a standard material choice in professional coffee equipment. This o-ring provides a reliable fluid seal at critical connection points within the machine, preventing leaks and maintaining proper system pressure. Installation is typically performed by an espresso equipment technician or a qualified service professional during routine maintenance or component replacement. This o-ring is used in commercial espresso machine service applications where a properly sized EPDM seal is required at group heads, boilers, valves, or other pressurized water-path components. It is a direct-replacement part referenced by the manufacturer part number 2280009, also cross-referenced under the supplier designation 04131. Service shops and on-site technicians sourcing OEM-spec replacement seals for NUOVA SIMONELLI equipment will use this part during scheduled maintenance or leak-related repairs.
