Description
Eliminate voltage drops and maintain a high-efficiency electrical circuit on your auto-transport equipment with the genuine Tweco 4-MPC Cable Connector Set (Part #9425-1400). While globally recognized as the gold standard in heavy welding shops, this complete male/female connector kit is the premier heavy-duty choice for commercial car haulers utilizing self-contained electric-hydraulic pump units on multi-car trailers.
When powering independent trailer ramps, split decks, and hydraulic lift gates from a tractors auxiliary power system, standard plug connectors often suffer from high resistance, heat buildup, and eventual melting. The Tweco 9425-1400 series solves this issue by offering a high-amperage quick-disconnect solution optimized for heavy-gauge 3/0 and 4/0 AWG battery cables. With a simple twist-lock action, it delivers an unyielding connection between your truck tractor and the trailers self-contained hydraulic power pack, ensuring your pumps run at full RPM without starving for current.
Key Features & Benefits
Optimized for Self-Contained Car Hauler Units: Delivers a reliable, high-capacity quick-disconnect link for the main positive and ground power feed lines going to your trailers electric hydraulic pumps.
Positive Cam-Action Locking: A swift twist-lock interface pulls both connector halves tightly together under high mechanical tension. This maximizes the metal-on-metal surface area to prevent high-amperage electrical arcing and power losses during heavy ramp adjustments.
Heavy-Duty Double Ball-Point Screws: Equipped with zinc-plated, dual ball-point internal cable screws that clamp tightly onto fine-strand copper power cables, preventing cable pull-out when the trailer turns tight angles.
Weather, Heat, & Oil-Resistant Boot Covers: Encased in heavy-duty molded rubber sleeves engineered to withstand continuous exposure to road grime, diesel fuel, hydraulic fluid, and extreme weather without cracking or leaking.
Complete 2-Piece Connection Pair: Comes packaged with 1x Male and 1x Female half, offering a complete, out-of-the-box solution to replace corroded truck-to-trailer auxiliary power plugs.
