Tweco 4-MPC-1 Female Cable Connector for 3/0-4/0 Cable

Reliable Power Connections with Tweco 4-MPC-1

When you are running heavy amperage through long leads, your connections are the critical link. The Tweco 9425-1422 Female Cable Connector (4-MPC-1) is built to handle the heat. Designed specifically for heavy-gauge 3/0 and 4/0 welding cable, this connector gives you the confidence that your power delivery is solid, safe, and efficient. Whether you are extending your leads across a shipyard or setting up a heavy fabrication station, Tweco's MPC series delivers the performance professional welders trust.

Forget about the hassle of soldering large cables. The 4-MPC-1 features Tweco's signature ball-point mechanical connection. You simply strip the cable, insert it into the brass body, and tighten the screw. The included copper shim protects your copper strands from breaking while ensuring maximum contact area for current flow. This means less resistance, cooler running connectors, and a stable arc at the workpiece. The female design mates perfectly with Tweco No. 4 male connectors, utilizing a positive cam-lock action that snaps in tight and stays put until you twist it apart.

Durability is built right in. The insulating cover is made from a special compound that stands up to abuse—dropped on concrete, dragged through oil, or exposed to sparks, it keeps on working. The recessed metal parts prevent arcing against grounded surfaces, adding an extra layer of safety to your setup. If you are building new leads or replacing worn-out ends on your heavy-duty machines, the Tweco 4-MPC-1 is the professional's choice for a quick, secure, and long-lasting connection.
