Condenser tube expander N series

for heat exchangers

Overview
The Torso N Series Expander is optimized for condenser applications such as oil coolers and radiators with small-diameter tubes. Its captive mandrel prevents internal (I.D.) scratching and the optimized feed angle enables high-speed operation for production environments. The tool is engineered for precise, repeatable expansions required in industrial tube-assembly processes.

Product Details
The N Series provides fast, repeatable tube expansion while minimizing the risk of internal damage. Construction uses corrosion-resistant materials to support continuous use with low maintenance. Typical applications include automotive heat exchangers, HVAC condensers, industrial cooling systems and general manufacturing operations requiring reliable tube joining.
