Abstract
Abstract A sealing apparatus is operative between a cable end and a cable termination and includes an elastomeric inner seal and an elastic outer seal. The sealing apparatus is for a cable end including a cable jacket and at least one cable member extending outwardly therefrom, with the cable termination including a base and at least one nipple extending outwardly therefrom. The elastomeric inner seal may have at least one nipple passageway for receiving and defining a seal with the at least one nipple, and at least one cable member passageway in communication with the at least one nipple passageway for receiving and defining a seal with the at least one cable member. The elastomeric outer seal may have opposing first and second open ends, with the first open end for engaging and defining a seal with the base. The elastomeric outer seal may also have an elastomeric inner seal passageway for receiving the elastomeric inner seal, and a cable end passageway extending in communication with the elastomeric inner seal passageway to the second open end for receiving and defining a seal with the cable jacket.
