Copper Tube Expander Aluminum Alloy Heating and Cooling Tube Expander Easy to Use Manual Swage Tool for Air Conditioner Repair

Built for heating and cooling and refrigeration maintenance, this aluminum alloy copper piping expander gives technicians a practical way to prepare tube ends by hand. As a repair tool, it is designed for everyday piping fitting jobs where a clean, controlled swage matters for a better connection.

The manual swage tool uses a double double sided layout that helps keep the body compact, so it is easier to handle when you are working inside narrow equipment areas or close to walls. The 7 in 1 style head and the listed sizes of 4, 5, 7.5, 10, 13.5, 15, 17, 18, and 22 mm cover a useful range for common copper tube tasks.

A built in reset spring makes the tube expander more comfortable to use over multiple cycles, since the handle returns smoothly after pressing. That means less strain when you are finishing several joints in a row, whether you are on a service call or doing regular workshop maintenance.

The overall size of about 155 mm in height and 154 mm in length also helps the hand swaging tool stay manageable in the hand while still giving enough leverage for controlled expansion. For air conditioner repair, refrigerator line work, or general copper piping setup, it offers a straightforward, manual approach that keeps you focused on the job instead of fighting the tool.
