Semi Truck 3-in-1 Air Lines Kit, 15 ft, 7-Way Plug

15 ft semi truck air lines kit restores clean, tangle-free air and ABS electrical routing between tractor and trailer for safer, more reliable hookups. This 3-in-1 spiral assembly combines dual rubber air brake hoses with a 7-way SAE-J560 ABS power line to replace worn, leaking, or messy lines. Built for heavy-duty service, it uses durable brass fittings and a sealing wrap to help reduce air loss, while the included hook keeps lines lifted to limit drag and abrasion.

• Replaces worn lines to reduce tangles, kinks, and messy routing between tractor and trailer


• Delivers tight connections with G1/2 brass spiral joints plus sealing tape to help minimize air leaks


• Supports trailer lighting/ABS with a 7-way SAE-J560 plug and pure copper conductors for steady current


• Resists wear with spiral wrap, rubber air hose with carbon black, and TPU-jacketed power line


• Includes a mounting hook to keep lines higher and reduce ground friction during turns and backing

Designed for quick replacement of standard ABS air/power line assemblies, this 15 ft combo line installs by connecting both air hoses and the 7-way electrical cord at each end, then securing the hook for a cleaner run. The spiral design helps prevent snagging and keeps connections organized, making coupling and uncoupling faster at the yard or dock. Keep seals inspected and connections tight for consistent braking air delivery and dependable trailer light operation. Grab yours today and refresh your tractor-to-trailer line setup.
