Description
Create seamless copper tube solder sockets without buying expensive copper fittings on commercial equipment installations. The Malco Products MalcoEdge TEMS Tubing expander kit swages soft copper lines using a mechanical scissor-action mechanism. This multi-size expansion kit handles refrigeration repairs and equipment piping. It cannot expand hard-drawn copper without torch annealing.
Drop-forged alloy steel handles provide mechanical leverage through long compound scissor linkage joints without handle flex. Precision CNC-machined expander head segments open in parallel to produce uniform, round tubing sockets that braze shut without solder voids. A durable black oxide finish coats the steel linkages to stop rust corrosion from humid equipment mechanical rooms. Contoured rubber handle grips absorb palm pressure during heavy swaging strokes on large tube diameters.
Mechanical Swaging Tool Hardware Details
Refrigeration contractors and commercial equipment technicians require dependable mechanical swaging tools to reduce braze joints on equipment installs. This manual kit speeds up line set connections on jobsites.
- Six interchangeable expander heads handle copper tube sizes from 3/8-inch to 1-1/8-inch
- Drop-forged alloy steel handles generate high expansion leverage on heavy copper tubing
- Precision segmented dies form concentric socket expansions to prevent braze voids
- Long compound linkages minimize hand grip squeeze force on large pipe diameters
- Quick-change threaded head interface allows tool-free head swaps in seconds
- Corrosion-resistant black oxide finish protects tool joints from humid basement rust
- Heavy blow-molded storage case keeps expander heads organized inside service vans
Mechanical Dyno Swaging Load Telemetry
Mechanical stress testing records 48 pounds of manual hand grip force required to swage 7/8-inch soft copper tubing. Die expansion diameter holds a 0.003-inch tolerance profile, producing tight solder clearance gaps that pull brazing alloy via capillary action. Scissor joint pivot pins withstand 1500 pounds of shear force without pin deformation. Hand grip deflection remains under 0.08 inches under maximum squeeze pressure.
HVAC Line Work Usability Bounds
Mechanics ream tube ends to remove internal copper burrs, thread the matching head onto the tool, and squeeze the handles together until the dies bottom out. Open the handles to extract the head. Do not use this manual swager on stainless steel or iron pipe.
- Linkage pivot joints require light motor oil application every forty service hours
- Expander head segments require cleaning with mineral spirits to remove copper dust
- Tube ends demand thorough reaming and deburring before inserting expander dies
Factory Warranty Tool Case Inventory
Malco Products backs this TEMS manual tube expander kit with a 1-Year commercial limited warranty. The kit contains the mechanical expander handle unit, six precision expander heads, inner-outer tube deburrer, and rugged carrying case.
