The coiled design allows the hose to stretch and retract as the slider moves, preventing tangling or kinking when the slider is locked in position. It connects the tractor’s air system to the slider's air cylinder, enabling the driver to adjust the fifth wheel fore and aft for proper weight distribution. Over time, constant flexing and exposure to road debris can cause cracks or leaks, leading to air loss and slider malfunction; the hose is replaced when worn or damaged.
