Do flex copper connectors act as dielectric connectors when used between

The connection may be self canceling electrolytically, but is not a
dielectric if metal to metal. A high line VOM can register a voltage
showing electrolytic activity if there is something happening.
Consider getting rid of your galvanized plumbing ASAP to avoid future
problems.
