8-5012 - Tweco 8-5012 Copper Crimp Ferrule for 4/0 Cable

Build Better Leads with the Right Hardware

When you are building custom welding leads or repairing a damaged ground cable, the quality of your connections defines the quality of your weld. The Tweco 8-5012 Cable Ferrule is the professional's choice for terminating heavy-duty 4/0 welding cable. If you have ever struggled with frayed cable ends that won't fit into a lug, or connections that get dangerously hot after a few minutes of welding, this simple copper sleeve is the solution you need.

Designed specifically for 4/0 cable, this ferrule slides over the stripped end of your wire, holding all those hundreds of copper strands tightly together. Once in place, you crimp it down using a hammer crimper or a hydraulic tool. The result is a solid, rock-hard end that provides a perfect path for your welding current. Because it is made of high-quality copper, it matches the conductivity of your cable, ensuring that you don't lose amperage at the connection point. This means a smoother arc and less strain on your welding machine.

Don't rely on electrical tape or messy mechanical clamps that loosen over time. Using a proper ferrule like the Tweco 8-5012 ensures your leads can handle the rough environment of a shop or job site. Whether you are replacing a worn-out stinger connection or building a long extension for field work, this ferrule gives you the peace of mind that your power delivery is secure. It is a small part that makes a huge difference in the longevity and safety of your welding setup.
