6-Piece Copper Pipe Expander Set, Professional Hand Tool for Copper Pipe Crimping with Drill Bit, HVAC Repair Kit

【High-Quality Material】The copper pipe expander is made of ball-bearing steel, giving it high durability and ease of use. The flares will always remain the same size and fit perfectly. The flaring has a perfect depth and a tight fit, which will facilitate brazing and reduce fatigue stress in the coupling area.【Reliable Quality】The flaring/stamping process will maintain the full ductility of the copper, ensuring superior overall coupling; the process will also prevent the pipe from cracking.【High Performance】The revolutionary system that uses heat to form the pipe by friction increases the contact surface between the flare and the valve, guaranteeing optimal durability and strength.【Purpose】The copper pipe expander is mainly used for air conditioning installation. It allows you to open up copper pipe to connect two pipes together. (It is mounted on an electric hand drill). The tool can also be used to replace old or damaged pipes. Features: High-quality material: The copper pipe expander is made of ball-bearing steel, which is practical and durable. The flares will always be the same size and fit perfectly. The flaring has a perfect depth and a tight fit, which will facilitate brazing and reduce fatigue stresses in the coupling area. Reliable quality: The flaring/stamping will maintain the copper's ductility, ensuring a better overall coupling; the process will also prevent the pipe from cracking.
