Tweco 4-MPC Male Cable Connectors (Master Pack of 24) - 3/0-4/0 AWG

Reliable Connections for Professional Welders

Keep your shop running smoothly with the Tweco 4-MPC Male Cable Connector Master Pack. This set of 24 connectors (Part Number 9425-1401) is the ultimate solution for outfitting new welding leads or replacing worn-out connections on your existing 3/0 and 4/0 AWG cables. Tweco connectors are legendary in the welding industry for their durability and ease of use, making them the preferred choice for welders who demand consistent performance.

The 4-MPC features Tweco's trusted ball-point cable connection system. Simply strip your cable, insert it into the brass body, and tighten the ball-point screw. The screw drives into the copper strands, creating a high-pressure contact area that ensures excellent conductivity and pull-out strength. No solder, no mess, and no waiting—get back to welding in minutes. The male connector is designed to mate perfectly with Tweco 4-FPC female connectors, using a half-turn cam-lock action that pulls the two halves together tightly for a low-resistance joint.

Safety and longevity are built into every unit. The heavy-duty insulating covers are designed to resist spatter, oil, and abrasion, extending the life of your leads in harsh shop environments. Whether you are running high-amperage Stick, MIG, or Flux-Cored processes, these connectors handle the heat without breaking a sweat. Buying in bulk with this master pack not only saves money but ensures you never get stuck with a bad lead in the middle of a critical job.
