A cylinder propelled through a conduit by the main fishing system is called a?

• A. Piston Cylinder
• B. Fishing Float
• C. Cable Pusher
• D. Conduit Piston

Answer: (D)

A conduit piston is designed to be propelled through a conduit by the main fishing system, serving as a piston that moves inside the conduit to push or pull objects along the run. The fishing system provides the motive force, pulling the piston through the confined space so you can advance or position equipment or cable without direct handling at the far end. The other terms don’t fit: a piston cylinder isn’t the standard descriptor for this tool, a fishing float is just a buoyant marker, and a cable pusher implies pushing the cable itself rather than moving a piston inside the conduit.
