PVC duct reducer couplings are pipe fittings used to securely join two sections of ductwork with different sizes. They are made to create a smooth, leak free transition for airflow within ventilation, fume handling, and exhaust systems. Reducer couplings work to reduce or expand the piping duct size to meet system design requirements and project needs in terms of volume, connecting components or equipment, and structural distribution. Manufactured from Type 1 Grade 1 polyvinyl chloride (PVC), our duct couplings meet ASTM D1784 standards and Cell Class 12454-B specifications. The couplers are made from high quality PVC for long lasting durability, chemical resistance, and service life for reliability across various use conditions and gaseous media. PVC duct reducer coupler sizes range from 3″ x 2″ up to 18″ x 16″ in diameter.
