This manual copper pipe tube expander is built for DIY homeowners, HVAC technicians, and plumbing professionals who need reliable, repeatable calibration results without power tools.\u003c\/p\u003e\n    \u003cp\u003eThe tool set includes multiple expander head models covering pipe outer diameters from approximately 12 mm to 32 mm (roughly 1\/2 in to 1-1\/4 in), with both straight and T-style configurations available. The expander cone and body are constructed from hardened steel with a smooth-finish working surface to reduce galling on soft copper tubing.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include expanding copper pipe ends for push-fit or compression fittings in residential plumbing repairs, calibrating refrigeration line sets before flare connections, and restoring out-of-round tube ends on HVAC copper pipe runs — all tasks where a manual tube expander for copper pipe delivers cleaner results than improvised methods.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed for soft copper tubing.
