PVC Duct Adapters

PVC duct flex hose adapters are transition fittings used to connect flex hose to rigid ductwork. They are designed to provide a secure, dedicated connection point between the different types of ductwork or between PVC duct systems and equipment. Duct flex hose adapters are used in systems, buildings, and equipment setups where rigid connections are impractical due to space, misalignment, or movement such as from vibrations. PVC duct adapters provide an airtight seal to effectively prevent leaks, ensure proper airflow, and maintain the integrity of the working ductwork to flex pipe connection. When properly installed and used, flex hose to duct adapters help hardworking systems accommodate vibrations, expansions, and contractions that may occur.

PVC duct adapter fittings are USA made by Harrison Machine and Plastic under the trade name SUPERDUCT®, one of the nation’s top manufacturers and brands of thermoplastic ductwork. PVC ductwork 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.

PVC duct adapter sizes range from 2″ up to 16″ in Iron Pipe Size (IPS) diameter. Large duct adapters in sizes up to 60″ in diameter may be available on request for unique projects. PVC flex hose adapters come in either hose spigot by belled socket or hose spigot by duct spigot connection options. For installation, a professional PVC primer and cement is recommended. For large duct adapters above 14″ in size, hot air PVC welding is recommended.

Harrison SUPERDUCT® PVC duct adapters are precision built and made from professional grade materials for overall superior quality, workmanship, strength, and performance. They are made to meet ductwork performance standards on material, mechanical, thermal, electrical, fire, and chemical compatibility properties and specifications

PVC duct adapters are used in the customization and assembly of various duct systems and configurations to create efficient, long term operational ventilation systems used in air distribution, exhaust handling, dust collection, and fume mitigation. They are corrosion resistant, lightweight, mechanically durable, and easy to install.

• PVC Material: Heavy duty thermoplastic with excellent corrosion resistance and durability that will not rust or degrade. 
• Chemical Resistance: Resistant to many acids, alkalis, alcohols and their gasses, fumes, and vapors. 
• Versatile: Designed to join flexible duct with rigid duct or equipment for completing system design and worksite projects.
• Hard Working: Engineered for long term service and minimal maintenance to keep ductwork systems running.
• Airtight: Will provide a secure, long lasting seal when properly installed.
• Easy to Install: Lightweight and impact resistant for easy handling and installation. 

Common applications and uses for PVC duct adapters include HVAC systems to connect air conditioning or heating units to ductwork, in industrial exhaust systems to vent fumes from equipment or processes, and in area collection systems requiring the removal and routing of air containing dust, particulates, vapors, or gasses from a work environment. They are also used in agricultural settings for ventilation systems in greenhouses or barns as well as in laboratories and manufacturing facilities as part of air quality and control systems.
