I would like some help on a question. A stainless steel flexible connector used to connect fiberglass piping with a metallic component, for example, needs to be protected from corrosion if its in contact with the soil. If a piece of corregated plastic or rubber piping is fit over the flex connector to isolate it from the ground, is it cathodically protected even if the connection is not water tight?

Kris: You don't state what type of stainless steel you are interested in. For cathodic protection to be effective, it needs a current path through the environment, i.e., ground. You cannot CP protect a metal with an air gap. David Hendrix The Hendrix Group Inc.

The connector is not protected unless moisture cannot get through the protective covering. What kind of stainless steel is it, and what kind of metal is it connected to? You can very easily get a galvonic problem between two different metals under these conditions.
