An electrical cable penetration seal apparatus which includes a compliant module having an inner and outer regions of different durometer characteristics. In some forms of the invention the outer regions are generally planar and disposed on opposed sides of the compliant module. The outer regions are manufactured of a relatively high durometer elastomer than an inner region which is made from a lower durometer elastomer.

An electrical cable penetration seal apparatus which includes a compliant module having an inner and outer regions of different durometer characteristics. In some forms of the invention the outer region has a higher durometer elastomer and a central region which is made from a lower durometer elastomer. The compliant module has an outer rectangular cross-section and the central region is a cylindrically shaped in some forms of the invention.

A method, and apparatus for practicing the method, is provided for the transit of one or more cables through an opening in a bulkhead while preventing electromagnetic interference and electromagnetic pulse energy from passing through the opening. A housing of electrically conductive material is positioned in the opening and secured around its full perimeter in electrically conductive contact with the bulkhead. The sheathing of each cable is treated so that the conductive shield of each cable is exposed. The cables pass through the housing with their exposed shield being within the interior of the housing. The end portions of the housing are sealed, such as by the use of deformable material. Electrically conductive material, such as shot, granules, powder, grease, liquids or the like, is used to fill the interior of the housing to form conductive paths between the shield of each cable and the housing. The material may be in the form of particulates, semi-liquid, or liquid, including conductive coatings.
