Vacuum Line Fittings, Automotive Vacuum Hoses & Connectors

Without vacuum, various components and systems will not work in your vehicle. It is important to inspect hoses and plastic connectors to make sure they are not cracked or leaking and replace as necessary or when swapping out vacuum-operated components.

Replacing old vacuum hose in your engine bay with new hose, such as silicone vacuum hose (available in different colors), can help add to great looks under the hood when used with fresh connectors and fittings. Silicone also lasts longer than standard rubber in most cases.

Automotive vacuum hose provides functionality to different vehicle systems, depending on the year, make, and model. The most common systems include the brakes (power brake booster), PCV system, transmission (modulator valve), ignition (vacuum advance), pop-up and hide-away headlights, cowl induction and grabber hoods, and windshield cowls, as well as heating and air conditioning systems with vacuum-operated vent doors.
