CPVC duct reducer couplings are pipe fittings designed to securely join two ductwork sections of differing sizes. They ensure a smooth, leak free transition for airflow within heavy duty ventilation, fume handling, and exhaust systems. Reducer couplings work by adjusting or expanding duct sizes to meet specific system design needs for airflow volume, connecting components, and achieving the necessary structural distribution. Manufactured from high quality chlorinated polyvinyl chloride (CPVC), these fittings offer superior temperature resistance, chemical durability, and long service life that makes them ideal for demanding environments. CPVC duct reducer couplers meet ASTM standards and are crafted for reliable use with various gaseous media. Sizes range from 3″ x 2″ to 18″ x 16″ in diameter, providing versatile solutions for many applications.
