  • Patent number: 9598926
    Abstract: A hydraulic cable injector includes a first stripper assembly positioned at a first end of the hydraulic cable injector to receive a cable and provide a lower seal. A first wye joint is coupled to the first stripper assembly, and a flow tube assembly is operatively coupled to the first wye joint. A second wye joint is coupled to the flow tube assembly, and a second stripper assembly is coupled to the second wye joint and proves an upper seal. A third stripper assembly is positioned at a second end of the hydraulic cable injector for injecting the cable into a tubing and providing a tubing seal. A separator interposes the second and third stripper assemblies and defines a central pathway to feed the cable into the third stripper assembly from the second stripper assembly.
