The Rebco GOS Single Conductor Cable Head provides both the mechanical and electrical connection between a single conductor wireline cable and the tool string. A spring-loaded contact plug ensures consistent, reliable electrical continuity between the surface cable and downhole instrumentation, even under the mechanical stresses of running and jarring operations. Used whenever downhole tools require surface-to-tool electrical communication, such as electronic memory gauges, BHP instruments, or other data-acquisition devices. Must be ordered by cable size to ensure a correct fit. Available 1 7/16" – 1 11/16" OD.
