Universal Defrost Duct Kit

The Universal Defrost Duct Kit by Vintage Air is a purpose-built HVAC component designed for classic and custom vehicle climate control systems. This defrost duct assembly delivers heated air to windshield defogging outlets, a critical function in vintage restorations and modern hot rod builds where factory air systems have been replaced or upgraded. The kit addresses the specific demand for proper defroster functionality in vehicles equipped with contemporary aftermarket air conditioning and heating units.

This defrost duct kit features a pair of black plastic hose assemblies engineered to direct conditioned airflow from the HVAC unit directly to windshield defogging vents. The 2-inch diameter hose diameter accommodates standard ductwork connections, while the overall assembly dimensions of 6.25 x 2.75 inches provide a compact footprint suitable for tight engine compartments common in vintage vehicle restorations. Plastic construction resists corrosion from engine bay moisture and heat cycling, ensuring long-term durability without the maintenance requirements of metal alternatives.

Professionals installing Vintage Air climate control systems in classic cars, street rods, and custom trucks rely on this defrost duct kit to complete proper airflow distribution and achieve full defroster capability. The kit's compatibility with Vintage Air's complete HVAC product lineup makes it an essential component for builders prioritizing authentic climate control in restoration projects. Installation requires connection to the defrost outlet ports on the main HVAC unit, with duct routing to existing or new windshield defroster vents.
