📌 Product Overview
The Ultimate Power Solution for Specialized Fleets.
Modern trailers demand more than just standard brakes and lights. Refrigerated units (reefers) and hydraulic liftgates require dedicated, high-amperage power feeds. Managing four separate lines across the deck plate is a tangled safety hazard waiting to happen.
Victory Technology’s 4-in-1 Air & Electric Connection Kit is the professional solution for consolidating complex connections. Engineered in our Zhuji Aoke facility, this heavy-duty assembly integrates two DOT Air Brake Hoses, one 7-Way ABS Cable, and one high-capacity Auxiliary Power Line into a single, organized bundle protected by a rugged spiral wrap.
🔹 Why Choose the Victory 4-in-1 Kit?
- ✅ Reefer & Liftgate Ready (The 4th Line):This kit goes beyond the standard. It includes a dedicated, heavy-gauge Auxiliary Power Line (typically Single or Dual Pole configuration) specifically designed to handle the high current loads needed to charge liftgate batteries or power reefer units reliably.
- ✅ 100% Pure Copper Power (No Voltage Drop):Auxiliary equipment fails if voltage drops. We use only Standard Gauge 100% Oxygen-Free Copper for both the 7-Way ABS cable and the Auxiliary Power Line. We never use cheap CCA (copper-clad aluminum), ensuring maximum power delivery in all weather conditions.
- ✅ All-in-One Spiral Protection:Four loose lines are a recipe for disaster. We pre-bundle everything in a Heavy-Duty Beveled Spiral Wrap. This keeps the lines suspended, prevents tangling on the catwalk, and provides armor against abrasion and cuts.
- ✅ DOT Certified Components:Safety is paramount. The Red and Blue air lines meet SAE J844/DOT FMVSS 106 standards. The electrical cables meet relevant SAE standards for heavy-duty trucking.

❓ Frequently Asked Questions (FAQ)
Q: What is the 4th line used for?
A: The 4th line is a dedicated high-power auxiliary cable aimed at supplying power to equipment like hydraulic liftgates or refrigerated trailer units, which require more current than a standard 7-way plug can provide.
Q: Is the auxiliary line pure copper?
A: Yes, absolutely. High-amperage applications require 100% Oxygen-Free Copper to prevent overheating and voltage drop. We do not compromise on this material.
Q: Is this kit difficult to install?
A: No. It is designed as a “Plug & Play” solution. All lines come pre-terminated with standard fittings (NPT for air, standard plugs for electric), and they are already bundled for easy routing.
