Expander Needles for Electric Tube Expander, Imperial Sizes, 4 pcs/set1/4,5/16,3/8,1/2,5/8,3/4,7/8")

These hardened metal die inserts are modular swap-in accessories for manual flaring tools, offered in 4 distinct sizing specifications to fit mainstream refrigeration copper tubing dimensions. The surface undergoes wear-resistant treatment to preserve precise flare shaping after repeated compression cycles.

Core Product Advantages

Size-differentiated interchangeable dies eliminate purchasing an extra standalone flaring tool for each pipe diameter, lowering overall hardware procurement expenses for HVAC technicians.

Hardened metal construction resists indentation under compression load, generating round, crack-free flare profiles to cut refrigerant leakage risks at pipe joints. Modular swap-in design streamlines size switching during mixed-spec piping construction.

Applicable Scenarios

The adapters serve refrigerant flare forming in residential and commercial air conditioning piping projects, refrigerator line repair, cold-storage servicing and automotive AC refrigerant piping jobs, compatible with standard manual flaring tool assemblies.
