Hydraulic Tube Expanding

hydraulic tube expanding

The HPX Series Tube Expanders are air driven hydraulic systems capable of producing expansion pressures up to 60,000 psi (4,134 Bar). When used in conjunction with HydroPro High Pressure Tooling, these systems offer the very best in tube expansion solutions.

The panel mounted LED's follow the expansion process through each complete cycle (indicated with green lights) Any failure to achieve or maintain expansion pressure or time is identified on the panel with a red light at the point of failure.


  • Direct pressure system - no clumsy intensifiers.
  • Process/Troubleshooting Indicator Lights track real-time expansion progress.
  • Easy to read analog or digital gauges.
  • eadouts in PSI and BAR.
  • Digital data storage available.
  • Built-in "dolly" style enclosure with large wheels for easy portability (HPX 6000 & HPX 6050).
  • Tube setting capability available
