20202072 - Tweco MPC-I Red Neoprene Insulator for MPC-1 Connectors

Keep Your Cables Safe and Identified

We've all seen them—welding cables wrapped in electrical tape because the original connector cover cracked or fell off. Don't let your gear get to that point. The Tweco Red Neoprene Insulator (MPC-I) is the proper replacement for your MPC-1 cable connectors. It’s built tough to handle the abuse of the shop floor. Whether you are dragging cables across concrete, over steel beams, or through greasy puddles, this neoprene boot stands up to the punishment better than cheap plastic or standard rubber alternatives.

Safety is the number one reason to keep your insulators in good shape. A bare connector is a live arc waiting to happen. If that brass touches your workpiece or the welding table when you aren't expecting it, you get arc flash, damaged parts, or a nasty shock. This Tweco insulator slides right over the connection to keep the current where it belongs. Plus, the red color isn't just for looks; it helps you instantly spot which cable is which. Use the red boot for your positive lead and a black one for your negative, and you’ll never have to trace the cable back to the machine to figure out your polarity again.

Installation is straightforward. The material is flexible enough to slide over the cable and connector body but snaps back to form a tight seal that keeps out grinding dust and water. It fits both the male and female ends of the MPC-1 setup, so you don't need different covers for each side of the connection. If your current connectors are looking a little ragged, or if the covers are held together by hope and tape, grab a fresh Tweco insulator. It’s a small investment that keeps your leads professional, safe, and ready for heavy-duty welding.

This is a genuine Tweco part, meaning it fits right the first time. No struggling with generic covers that are too loose or too tight. Keep a few in your toolbox so you can swap them out the moment you see a cut or crack in your old ones. Your cables are your lifeline to the arc—protect them properly.
