Abstract: An apparatus for providing dual metal to metal seals for sealing tubing encapsulated conductors or hydraulic tubing is disclosed. The apparatus utilizes a unitary, metal seal body that provides an external sealing surface for a first metal to metal seat and an extended portion that energizes a second metal to metal seal. The unitary metal seal body may have a forward end, a midsection, a back end, and an internal passageway proceeding from the back end through the forward end for receiving a tubing encapsulated conductor or hydraulic tubing. The unitary, metal seal body may utilized together in a system with a forward nut, a rear nut, an electrical or tubing connection housing, and three metal ring seals.

Abstract: An electrical connector having no glass seals, while having a single electrical conductor embedded in a thermoplastic body, with a section of the electrical conductor also being enclosed within a insulating ceramic bushing, wherein the electrical conductor has an enlarged diameter portion sized to allow the enlarged portion to sealingly engage one end of the ceramic insulating bushing, wherein such engagement prevents the extrusion of the thermoplastic body along the electrical conductor through the interior of the insulating ceramic bushing. Alternative embodiments include electrical connectors having multiple pin electrical conductors and downhole sensors.
