The vacuum hose is a flexible connection that directs the vacuum of the auto collector to supply various components of the vehicle, like the brake booster, the positive crankcase ventilation (PCV) valve, the heater control valve, HVAC control and exhaust gas recovery (EGR valve).

Suction hoses are flexible tubes specifically designed to create a vacuum for the purpose of transferring liquids, gases, or solids from one location to another. They operate by using the principle of negative pressure, drawing materials into the hose through a suction force.
