    Abstract: An entrance bushing for an electric treater subject to high voltage, temperature and pressure operating conditions. The bushing mounts in the treater by a threaded adapter on one end of an interiorly extending cylindrical Teflon member. First and second sleeves with closed ends are threaded into the member to extend coaxially from a longitudinal passage receiving an electrical conductor connected between an external power source and internal electrical treater components. Any fluid leaking between the adapter and member is vented exteriorly of the first sleeve and passage. The second sleeve is permanently bonded and sealed to the member by a polymer sealing element (fluorinated ethylene propylene resin) compressed between interengaged threads to exclude voids and mechanical-thermal induced seal disruption. A third sleeve encloses the second sleeve with an electrical interconnection provided by a flexible lead to isolate the sealing element from mechanical impacts.
