Electrical connector assemblies and methods for forming and using the same

An electrical connector for use with a conductor includes a housing, a conductor member and a flowable sealant. The housing defines a port. The port includes: an entrance opening; an exit opening; and a conductor passage extending between and communicating with the entrance and exit openings, the conductor passage being adapted to receive the conductor therethrough. The conductor member is disposed in the housing. The sealant is disposed in the conductor passage. The sealant is adapted for insertion of the conductor therethrough and to the conductor member such that the sealant provides a seal about the inserted conductor. The sealant is positively pre-pressurized prior to insertion of the conductor into the sealant.
