Features include heavy-duty 1/2″ NPT brass swivel fittings, protective stainless steel spring guards, and dual die-cast zinc 7-pole plugs. Select from 5 fleet configurations, ranging from standalone Red/Blue Air Coils (Suzi Lines) and 7-Way Power Cords to complete 3-Piece Combo Kits with color-coded anodized aluminum extension grips and glad hands. Shipped directly from our Wheeling, Illinois warehouse.

Product Overview

Eliminate hazardous sagging lines, kinks, and frame rubbing with our Commercial Coiled Air Brake Hose & 7-Way Electrical Cable Series. Designed for long-haul rigs, fleet trucks, and heavy equipment, these high-recoil assemblies expand effortlessly during sharp turns and retract tightly to prevent deck-plate entanglement and roadside inspection citations.

Manufactured from high-grade virgin PA12 nylon and cold-weather polymer jackets, our air coils resist abrasion, engine oil, road salt, and UV exposure. The 7-way electrical cable utilizes heavy-gauge copper wiring sealed inside a weatherproof green jacket to deliver reliable power to trailer ABS systems, brake lights, and turn signals. Available in individual components or complete ready-to-install 3-piece combo kits with ergonomic aluminum handles and glad hands.

Key Performance Advantages

• Full DOT & SAE Compliance: Air lines meet SAE J844 / FMVSS 106 standards for commercial air brake systems; 7-way power cords meet SAE J560 / SAE J2394 requirements for ABS electrical circuits.

• Superior Spring Memory & Anti-Sag: Advanced thermal-set nylon and TPU coil construction resists sag and stretch fatigue over tens of thousands of dynamic expansion cycles.

• All-Weather Resilience: Maintains high flexibility and structural integrity in extreme temperature conditions ranging from -40°F to +200°F (-40°C to +93°C).

• Heavy-Duty Strain Relief: Plated stainless steel spring guards protect 1/2″ NPT brass swivel fittings from strain fractures during sharp tractor-trailer articulation.

• Weatherproof Electrical Plugs: Solid die-cast zinc 7-pole male plugs feature dual cable guards and weather-sealed terminals to prevent corrosion and intermittent electrical shorts.
