12 ft semi truck air line kit keeps your trailer connections organized to reduce tangles, leaks, and downtime. This 3-in-1 combo line bundles two air brake hoses with a 7-way SAE J560 ABS power line for dependable brake response and steady lighting power. Spiral-wrapped hoses help prevent snagging, while glad hands, handles, seals, and a spring kit support a tighter, more secure hookup.

Designed for tractor-trailer setups that need a cleaner, more reliable connection between tractor and trailer, this air brake hose and 7-way electrical combo helps protect lines from shaking, ground friction, and daily wear. Keep seals in good condition for consistent performance, and disconnect/store glad hands properly when parked to extend service life. If your current lines are cracked, leaking, or constantly knotting up, grab yours today and get your connection point back under control.
