What is metal swage?

A metal swage is a tool used in metalworking to shape and flare the end of a pipe or tube. It is typically used to create a strong, leak-free joint between two sections of metal piping or tubing, thereby making it an essential tool for plumbing and mechanical work. A swage can be used with a variety of different metals, including steel, copper, brass, and aluminum, and can create a range of different flared shapes depending on the specific needs of the job. Many modern swages are designed to be compact and portable, making them easy to use in tight spaces or on job sites where mobility is important.
