It carries compressed air from the air compressor to the air dryer or air tank, which is critical for the vehicle's brake and suspension systems. Over time, these lines can corrode or crack, leading to air leaks and pressure loss, so they need to be replaced when damaged. The assembly includes brass fittings and a steel tube with a zinc cobalt coating for corrosion resistance.
