Description
Expand refrigeration copper tubing and HVAC lines without leaky braze couplings or hand-pumping fatigue. The Malco Products MalcoEdge HYE Hydraulic tube expander kit swages soft copper and aluminum tubing on commercial jobsite installations. This hydraulic expander kit creates precision solder joints on commercial refrigeration lines. It cannot expand rigid hard-drawn copper without prior annealing.
A compact hydraulic power head houses a forged steel piston mechanism that delivers immense outward mechanical force via smooth pump lever strokes. Precision-machined expander heads feature segmented hardened steel dies that expand tubing evenly without splitting copper walls. An angled head design provides tool clearance inside tight HVAC equipment cabinets and ceiling joist spaces. The heavy-duty aluminum tool body resists mechanical shock from accidental drops onto concrete shop floors.
Hydraulic Tube Expander Build Specs
Commercial HVAC technicians and equipment mechanics depend on hydraulic swaging tools to eliminate expensive copper coupling fittings and reduce brazing joints. This kit creates strong socket connections in seconds.
- Hydraulic pump mechanism generates high outward force to expand heavy copper tube walls
- Six interchangeable expander heads accommodate tube sizes from 3/8-inch up to 1-1/8-inch
- Segmented steel expander dies distribute expansion force around tube circumferences
- Angled tool head configuration allows expansion inside cramped mechanical equipment cabinets
- Single-stroke pressure release button collapses expander dies for quick tube removal
- Cast aluminum body cuts tool weight to prevent arm fatigue during overhead work
- Heavy-duty blow-molded carrying case protects expander heads from jobsite impact damage
Expander Bench Pressure Load Telemetry
Hydraulic dyno testing measures 2800 PSI internal fluid pressure inside the expander head during swaging cycles on 1-1/8-inch refrigeration copper. Segment expansion tolerances remain within 0.002 inches of true roundness across 1000 continuous test swages. Copper socket depth measures 0.45 inches on 3/4-inch tubing, exceeding standard braze joint depth requirements. Hand lever actuation requires 18 pounds of pump stroke force.
Refrigeration Line Swaging Negative Filter
Technicians deburr the inside of the cut copper tube, thread on the correct size expander head, and pump the hydraulic handle until the head seats. Press the release trigger to extract the tool. Do not use this tool on steel conduit or un-annealed hard copper pipe.
- Expander head cone segments require light machine oil lubrication every twenty uses
- Hydraulic head piston seals demand visual inspection for fluid weeping every month
- Internal copper tube deburring requires verification before inserting expander heads
