Review: 2 seals as ordered - Received 2 seqls as ordered, didn't use them therefore cannot judge if they fit for Delonghi Dedica EC685 espresso machine Review: Does not fit De’Longhi Dedica EC685 – deforms under pressure - I bought this seal set for my De’Longhi Dedica EC685, but unfortunately it does not fit properly. Both seals twist and deform out of shape on the first espresso pull, causing water to leak around the portafilter. I installed them carefully and confirmed it wasn’t a fitting error; the material is too soft and the size slightly off for the EC685. These are not suitable replacements for the genuine De’Longhi gasket. Would not recommend for Dedica EC685 owners. ## Features - ☕【51mm Silicone Steam Ring For Espresso Machines】 Silicone Steam Ring compatible for Delonghi EC680/685/785/885/850/860,La Specialista EC9335M/EC9355M/EC9665M Coffee Maker etc. - ☕【Food Grade Silicone Material】 The Silicone Steam Ring of the coffee machine is made of high-quality silicone material, which is safe and durable, non-toxic, flexible and safe to use, more resistant to high temperature than ordinary rubber gaskets, and has a longer life. - ☕【Excellent Sealing Ability】 No BPA grouphead gasket replacement part soft silicone fits into grooves very easily, resulting in a tight and secure fit that seals to ensure no moisture escapes while minimizing necessary changes frequency. - ☕【Size】 The inner diameter of the brewing head gasket of the coffee machine is about 4.6cm/1.81inches and the outer diameter is 5.9cm/2.32inches inches.
