46 IN DISCHARGE HOSE

This is a heavy-duty discharge hose that carries hot compressed air from the truck's air brake compressor to the air dryer or wet tank. It has female SAE swivel fittings on both ends, making installation easier and reducing stress on the hose from engine vibration. Over time, heat, flexing, and age can cause the hose to crack or leak, leading to air loss and longer compressor run times, so it's replaced to keep the air system tight and braking reliable.
