Group Bell O-ring This EPDM o-ring seals the group bell on a wide range of commercial espresso machines. EPDM is the standard compound for hot-water and steam contact points, resisting heat and mineral scale better than general-purpose rubber. SPECIFICATIONS Size: O-ring 03187, EPDM Cross section: 2.62 mm 52 mm outside diameter x 47.30 mm inside diameter COMPATIBILITY Fits: Bezzera, BFC, Brasilia, Elektra, Reneka, SAB Italia, Saeco, San Remo, Spaziale and Victoria Arduino group bell assemblies that share this o-ring spec. INSTALLATION DIY-friendly — lightly lubricate with food-safe grease before seating in the group bell groove. PRO TIPS A flattened or brittle o-ring here is a common source of leaks around the group bell joint; replace at the first sign of dripping or seepage from that seam.
The catalog often lists the same model at several merchants — worth a price check before you buy.
