EPDM O-Ring (OR 02012) for Cimbali, Faema & San Marco Hydraulics Genuine-spec EPDM o-ring sized to the OR 02012 standard, used as the sealing ring inside Cimbali and Faema auto-frother assemblies, the La San Marco 95 hydraulic circuit manifold, and Marcfi manual-fill valves. EPDM compound holds up to hot water and steam contact far better than a standard nitrile o-ring. SPECIFICATIONS Standard: OR 02012 Material: EPDM (steam/hot-water rated) COMPATIBILITY Fits: Cimbali/Faema auto-frother assemblies; La San Marco 95 hydraulic circuit manifold; Marcfi manual-fill valves (position #8 in the manifold diagram) Replaces: Cimbali 401-368-000, Colged 456014, Elettrobar 456014, Faema 401368000 / 4701030139, Gaggia 12001614, Giga 456014, MBM 456014, Saeco 12000890 / 12001614 / 140326561, San Marco 109109 INSTALLATION A simple o-ring swap for anyone comfortable opening a hydraulic manifold; no tools beyond basic hand tools required. PRO TIPS EPDM (not nitrile/NBR) is the correct compound for this position because it's in constant contact with hot water and steam, a generic nitrile o-ring here will harden and fail within months. Lightly grease the o-ring with food-safe silicone grease before reinstalling; it seats easier and lasts longer against the wear of the manifold.
