The AIR FLOW PRODUCTS 84RAT06 is an airtight stick-on takeoff fitting designed for round duct pipe. It provides a sealed branch connection point on round duct systems without requiring sheet metal cutting tools or mechanical fasteners for initial positioning. The adhesive-backed collar creates a tight seal at the takeoff point, reducing air leakage and maintaining system static pressure. HVAC sheet metal installers and duct fabricators use this fitting in residential and light commercial duct distribution systems where round branch takeoffs are required.
The 84RAT06 is suited for new construction and retrofit duct installations where round branch runs connect to a main duct trunk or plenum. The 6-inch diameter fits standard round duct and flex duct collars commonly used in residential forced-air systems. The stick-on design speeds up branch layout during rough-in, making it a practical choice for production homebuilders and HVAC contractors working on tight schedules.
Designed as an OEM-style replacement and new-installation fitting for 6-inch round branch takeoff applications in residential and light commercial forced-air duct systems.
Installation is performed by qualified HVAC technicians or sheet metal installers. Shut down the air handler or furnace and confirm the system is not pressurized before making any duct modifications. Clean and dry the duct surface thoroughly before applying the adhesive-backed collar to ensure a proper seal. Supplement the adhesive bond with sheet metal screws and UL 181-rated tape or mastic sealant per local mechanical code requirements.
