AOOWU Self-Adjusting Cable Crimping Tool with 1,800 Ferrules, 0.08–16 mm²

For wiring a household appliance, an automotive connection or an electronic component, this AOOWU crimping set brings the tool and cable-end ferrules together. Its self-adjusting mechanism works across a 0.08–16.00 mm² range. The set includes 1,800 ferrules in eight sizes, sorted by colour, for different cable requirements.

Everyday use

Choose a ferrule to suit the cable, strip back enough insulation to expose the conductor, and position the ferrule over the cable end. The crimper’s six serrated surfaces close together to form a hexagonal crimp around the cable and cylindrical terminal. This is a practical setup for repeat wiring tasks, from home DIY to work on device switches, automotive and household wiring, electronic components with pins and industrial connections.

The self-adjusting design adapts to the selected ferrule size, helping make the crimping process more consistent and reducing wasted terminals. Once the required sleeve size is set, a positive lock keeps the adjustment in place, the lock can also be released. The handle uses lever action to make pressing easier, while its wider, non-slip grip is designed for comfortable handling during everyday use. For jobs that call for several ferrule sizes, having a selection in the set means you can choose the terminal to match the cable rather than relying on a single-size approach.

Strengths

The hexagonal crimp profile is formed by six jaws acting at the same time. This gives the cable end a close-fitting crimp and helps protect thinner cables from abrasion during the process. The self-adjusting action and lockable setting support repeat work across the tool’s stated range, while the supplied ferrules cover a variety of cable specifications.

Use the set for wiring work around the home, on automotive connections, or with electronic components and industrial wiring. Before crimping, match the ferrule to the cable size and position the joint in the pliers. After use, clean any liquid from the tool to help prevent rusting. A small amount of lubricating oil may be present on the tool’s surface to protect it from oxidation, it does not affect its use.
