3-in-1 semi truck air lines kit keeps trailer air brakes and electrical power organized for cleaner routing and more reliable connections. This 15 ft combo line replaces worn or tangled ABS air and power lines with two air hoses plus a 7-way SAE-J560 electrical cord, using spiral wrap to reduce snagging. Glad hands, handles, seals, and mounting hardware are included to help minimize air leaks and maintain consistent brake response.

Built for daily road use, this combo airline set simplifies installation versus separate, loose ABS and air lines—connect both ends, hang with the hooks and tender spring, and you’re ready to run. The air hoses use durable rubber with anti-static properties, while the power cord is protected by temperature-resistant TPU sheathing to handle tough conditions. Keep spare seals on hand and replace them when wear appears for consistent coupling performance. Grab yours today and get your tractor-trailer connections back in order.
