This hydraulic swaging tool covers 3/8" to 1-1/8" OD with seven expander heads to match common copper, aluminum, brass, titanium, and soft steel lines. The hydraulic mechanism delivers controlled expansion, while the included deburring tool and pipe cutter help prep clean edges for safer, smoother fittings.

• Delivers controlled hydraulic expansion to form consistent swages with less hand strain than manual expanders.


• Includes deburring tool to smooth ID/OD edges, reducing snags and helping fittings seat cleanly.
