A Flexible Shaft for Tube Cleaning is a specialized type of flexible shaft designed specifically for cleaning the inner surfaces of pipes, tubes, or condensers — commonly used in boilers, heat exchangers, chillers, and HVAC systems.

It’s a rotating flexible cable encased in a protective sheath, which drives a cleaning tool (like a brush, cutter, or buffing head) inside narrow or curved tubes. The flexibility allows it to navigate bends or long, straight tube paths.
