12″ to 8″ Pre-Conditioned Air (PCA) Hose Reducer for use with aircraft air conditioning and heating units. Reduces PCA duct diameter size to 8″, the aircraft inlet adapter size. This hose component transitions PCA tubing diameter.
This tapered, straight PCA reducer connects 12″ LayFlat or Wire-Reinforced PCA hoses to the aircraft coupling, allowing pre-conditioned air to enter the aircraft. Constructed of polyester reinforced flame-resistant PVC fabric, the PCA reducer will safely alter the diameter of your heating or cooling hose. Designed for service in aircraft applications.
