Expander Heads for Electric Tube Expander, 5 pcs/set（1/4,3/8,1/2,5/8,3/4")--Wire-Cut Version

These modular black hardened alloy die inserts come in five distinct pipe diameter specifications, engineered to be swapped into matching flaring tool fixtures. The wear-resistant surface treatment reduces compression-induced abrasion during repeated flare forming, securing consistent workpiece quality for daily HVAC field servicing.

Core Product Advantages

Five graded size options cover the mainstream copper tubing sizing range used in refrigeration projects, removing the need to buy separate dedicated flaring tools for different pipe dimensions and cutting overall hardware procurement expenses.

Hardened alloy material resists indentation under compression loads, crafting round crack-free flare profiles that lower refrigerant leakage risks at pipe joints. The plug-and-play modular design enables quick size swaps during mixed-spec piping construction.

Applicable Scenarios

These die adapters are deployed for flare forming work in household and commercial air conditioning refrigerant piping, refrigerator refrigeration line reworking, cold-storage piping adjustment and automotive air-conditioning pipe servicing, compatible with standard manual flaring tool assemblies for soft copper tubing.
