CheeMuii 12FT Semi Truck Air Lines Kit 3-in-1 Air Hoses for Truck

The CheeMuii 12FT Semi Truck Air Lines Kit combines electrical and air connections into a single wrapped assembly for tractor-trailers. Designed to simplify hookups between the engine and trailer, this kit delivers a complete replacement setup that replaces worn-out lines without requiring you to purchase individual fittings separately.

The assembly includes a 7-way electrical cord alongside dual 3/8-inch ID air hoses. The power line utilizes a zinc die-cast plug compliant with SAE J560 testing requirements, transmitting power reliably to your trailer. Both ends of the ABS power cable feature 3.94-inch stainless steel springs that provide wire cushioning during hookup, while the green ABS cable itself is rated to perform in temperatures as low as -65 degrees Celsius (-85 degrees Fahrenheit).

To keep the lines elevated and secure, the kit includes a 25-inch tender spring made of galvanized carbon steel and a clamp built from 304 stainless steel and rubber. This hardware supports the lines and buffers road motion. In addition, the set provides a pair of glad hands and four rubber seals, matching standard replacement specs for common parts from Phillips, Tectran, Velvac, and Bendix.

One limitation to consider is that the kit comes exclusively in a 12-foot length, which may not fit tractor-trailer setups requiring longer runs. Buyers must also verify that their specific vehicle configurations match the listed replacement part numbers for the glad hands and tender spring.

Verdict: This complete 12-foot air line and electrical kit is an ideal choice for truck drivers and fleet owners looking for a direct, certified replacement that withstands severe cold weather. It provides all necessary mounting hardware and glad hands in a single package.
