Flat Isolating Gaskets
Flat isolating gaskets are available in a wide variety of dielectric materials to eliminate the possibility of electrical currents passing through the flange. For additional protection, type “E” gaskets extend out to the O.D. of the flange to help eliminate the possibility of any metallic materials inadvertently becoming lodged between the flange faces and thus shoring-out the desired electrical isolation.
