Tube flaring and swaging are both processes used to modify the ends of tubes, but they serve different purposes and involve distinct techniques. Tube flaring is a process used to expand the end of a tube to create a conical shape. This is typically done to ensure a secure and leak-proof connection with a fitting. The flared end of the tube fits over a fitting, and a nut is used to hold the connection in place. Flaring is commonly used in plumbing, automotive brake lines, and HVAC systems. The most common types of flares are the single flare and the double flare, with the latter providing extra strength and durability. Swaging, on the other hand, involves reducing the diameter of a tube or creating a tapered end. This process is used to join two tubes of different diameters or to prepare a tube for insertion into a fitting. Swaging can be done using a swaging tool that compresses the tube end, or through rotary swaging, which uses a series of hammers to shape the tube. Swaging is often used in metalworking, HVAC systems, and in the production of musical instruments. In summary, the primary difference between tube flaring and swaging lies in their objectives: flaring expands the tube end for fitting connections, while swaging reduces or reshapes the tube end for joining or insertion purposes.
