Swaging & Flaring Tools

Swaging and flaring tools are used to reduce or increase the diameter of tubes and pipes. They are commonly used for automotive parts repair. The swaging tool can be either a handtool or a mechanical device that compresses the tube or pipe by rotary hammering. The flaring tool is used with the swaging device to measure and prepare the diameter of the pipe or tube.


The swaging handtool is a device that activates compression by squeezing the handles or pushing the release lever. The tube or pipe is placed in the cavity of the swaging tool and the tool is clamped to adjust the diameter of the pipe or tube. These types of swaging tools can also be used to adjust metal sleeves for wire cables. Compression may take place several times to achieve the desired results.


Swaging machines can be portable or mounted. Some are manually operated, whiles others are driven by power. These types of swaging machines are able to handle galvanised stainless steel cables and pipes, and are considered to be more for industrial use.


The flaring tool is a device that consists of a set of bars lined with holes to match the diameter shape of the pipes. The most common types of flaring tools are single flares and double flares. Single flares are designed for carrying low-pressure fluids, for example, fuel lines. Double flares are commonly seen in brake systems because they carry higher pressures.
