Air Flow Products 84AT08 Airtight Stick-on Takeoff 8 Inches

Product Description

The AIR FLOW PRODUCTS 84AT08 is an airtight stick-on takeoff fitting designed for flat duct systems. It provides a sealed branch connection point, allowing supply air to be tapped off a flat duct run without cutting rigid collars or framing additional support. The adhesive-backed design simplifies field installation and helps minimize air leakage at the takeoff joint. At 8 inches, this fitting suits standard residential and light commercial trunk-and-branch duct layouts. HVAC technicians and sheet metal installers use this fitting where airtight performance at branch connections is required.

The 84AT08 is suited for residential and light commercial HVAC duct systems using flat duct configurations. It is a common choice in new construction and retrofit applications where branch takeoffs need a reliable, low-leakage connection to a flat trunk duct. The stick-on mounting method allows placement without sheet metal screws at the attachment point, making it practical for accessible plenum and crawlspace installations.

Key Features

• Airtight construction reduces air leakage at branch takeoff connections
• Adhesive stick-on mounting eliminates the need for additional mechanical fasteners at the duct face
• 8-inch size fits standard residential and light commercial duct branch openings
• Designed specifically for flat duct systems, ensuring proper seating and seal integrity
• Simplifies installation in tight or confined spaces such as crawlspaces and shallow plenums

Compatibility

Designed as an OEM-style replacement and new-installation fitting for flat duct systems requiring an 8-inch airtight branch takeoff connection.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal installers. Before installing, shut down the air handling unit and verify the duct system is depressurized. Clean and dry the flat duct surface thoroughly before applying the adhesive backing to ensure a proper seal. Work should conform to applicable mechanical codes and local jurisdiction requirements for duct leakage standards.
