This gasket kit provides complete protection of both flange faces with the same outside diameter as the flanges. This design prevents foreign matter collection between flange faces to ensure complete cathodic isolation.
Manufactured to fit only the raised face surface of flanges. The outside diameter is slightly less than the inside diameter of the bolt circle. Recommended flange wrapping prevents foreign material from "shorting out" the flanges.
Specialized design for ring type joint flange configurations, providing reliable insulation and sealing performance.
