Preparing Copper for Swaging:

1. Cut the pipe: Use a hacksaw or pipe cutter to get a clean, square cut.

2. Ream the end: Remove any burrs from the inside of the cut end using a reamer.

3. Soften the pipe (if using hard copper): Heat hard copper pipe until it is bright red, then let it cool or quench it in water to make it soft and malleable. Soft copper is essential for successful swaging.

Benefits:

Precision-designed hydraulic swaging expander head creates perfect socket connections on 3/8" copper tubing for leak-free soldered joints. Expands copper tube ends uniformly and consistently using controlled hydraulic pressure, ensuring proper fit for joining tubes. Essential for creating professional socket connections in refrigeration lines and plumbing installations where soldered joints are required. Hydraulic swaging provides superior results - consistent expansion, precise control, less operator effort, and faster operation. Hardened steel construction ensures the expander head maintains its precision through repeated hydraulic pressure cycles. Creates even, controlled expansion that prevents distortion or weak spots. Perfect for HVAC/R technicians installing refrigeration lines, plumbers working with copper pipework, and professional installers requiring reliable tube expansion capability. Creates leak-free connections that withstand pressure and vibration in refrigeration and plumbing systems. The precision hydraulic expansion ensures proper clearance for solder flow whilst maintaining tube strength. Works on soft copper or properly annealed hard copper. Essential accessory for any technician who regularly creates soldered connections on 3/8" copper tubing using hydraulic swaging equipment.
