99402124 - Tweco Replacement Cover for MPC Cable Connectors

Genuine Tweco Replacement Insulation

The Tweco 9940-2124 Connector Cover is a critical replacement component designed to maintain the safety and operational integrity of your welding cable assemblies. Engineered by Tweco, a leader in welding accessories, this cover is specifically manufactured to fit Tweco MPC (Mechanical Power Connector) series cable connectors. In industrial environments, the insulating covers of cable connectors are often subjected to extreme wear, dragging across concrete floors, exposure to hot sparks, and contact with oils and solvents. Over time, this can degrade the material, leading to cracks or splits that compromise electrical safety. This replacement cover allows maintenance teams to refurbish existing cable leads without the expense of replacing the entire connector assembly.

Constructed from high-durability synthetic materials, the cover provides robust electrical insulation, preventing accidental contact with the live metal connector body. This is essential for compliance with workplace safety standards (OSHA/CSA) regarding welding lead maintenance. The material is formulated to resist hardening or cracking over time, even in fluctuating temperatures typical of welding workshops and outdoor field sites. Its ergonomic design not only protects the connection but also provides a secure grip for welders when twisting connectors to lock or unlock them. By keeping a stock of these replacement covers, MRO managers can ensure that downtime due to damaged cable leads is minimized and that all welding equipment remains in safe, inspection-ready condition.

Installation is straightforward, designed to slide over the cable and seat firmly onto the connector body, ensuring a tight seal that helps keep out dirt and metallic dust. Whether you are repairing a single station or refurbishing a fleet of welding leads, the Tweco 9940-2124 offers the reliability and fitment guarantee that comes with using genuine OEM parts.
