CPVC Duct Adapters

CPVC duct adapters are used to create secure connections between segments of flexible duct to rigid duct lines in CPVC built ductwork systems. The adapters are also used to attach ductwork to other components or equipment used in HVAC systems, ventilation networks, fume scrubbers, and filtration systems. These adapters are made from chlorinated polyvinyl chloride (Corzan® CPVC), an industrial grade, heavy duty thermoplastic known for its durability, chemical resistance, and high working temperature range. CPVC duct adapters, also known as flex hose adapters, provide a transition piece and position for connecting ducts or equipment of different sizes, shapes, or materials. The adapters feature a smooth bore to minimize airflow restriction, with one end made to fit snugly into or over ductwork and the other end made to match the equipment or duct section to be connected. CPVC duct adapters are used for their superior resistance to corrosion, chemicals, and temperature extremes compared to metal or other plastic materials. This resistance makes them ideal for hardworking industrial and commercial applications that handle corrosive fumes, chemical gasses, exhaust, dust, particulates, or operate at high temperatures. Flex hose adapters are used to modify, extend, repair, or complete the installation of CPVC ducting systems.

These are USA made CPVC duct adapters built by Harrison Machine and Plastic® under the trade name SUPERDUCT®, one of the nation’s top manufacturers and brands of thermoplastic ductwork. SUPERDUCT® flex hose adapters are to be used with air and compatible gaseous media in open air, non-pressurized applications only. They are not for use in pressure systems, with liquids, or with known incompatible chemicals. Always verify chemical compatibility prior to use. 

CPVC duct adapter sizes range from 2″ to 12″ in Iron Pipe Size (IPS) sizing standard for use with IPS or Schedule 40 ductwork. CPVC flex hose adapters come in either hose spigot x belled socket or hose spigot x duct spigot connection options.

CPVC duct adapters are manufactured from professional grade Corzan® CPVC that meets FM4910 specifications and ASTM D1784 requirements. CPVC duct flex hose adapters meet and/or exceed industrial ASTM testing standards for product quality, mechanical strength, chemical durability, and physical properties related to working temperature, fire, flame spread, and smoke generation. Their technical specifications ensure enduring connections and heavy duty performance.
