SEMI-COMMERCIAL MODEL USERS BEWARE!
Models such as the Expobar, ECM Giotto, Isomac, and Quickmill claim to have an E-61 group head, and for the most part they are, but we have found that these gaskets are a bit too tight on the inside diameter. We recommend you contact your dealer (or someone who sells the units new) for the specific gasket for that particular unit.
