Abstract
Abstract 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.
