isolation gasket installedIsolation gaskets (Flange Insulating Kit) are used to stop the current flow across metallic pipelines by separating two flanges. The isolation of these pipeline segments allows cathodic protection for underground and above ground pipelines to control the stray electric current flow.

Isolation Gasket Type E

A full face insulating gasket centers the gasket within the flange by the bolts. This gasket covers the whole face of the flange making it less likely of a short across the flanges by any foreign material.
