Air Flow Products 84RAT9 Stick-on Takeoff Round Pipe 9 in

Product Description

The AIR FLOW PRODUCTS 84RAT9 is an airtight stick-on takeoff fitting designed for round duct pipe. It provides a sealed branch connection point on a main trunk or round duct run without requiring sheet metal screws or mechanical fasteners for initial attachment. The adhesive-backed design allows for faster field installation and reduces air leakage at the branch tap point. HVAC technicians and sheet metal installers use this fitting in forced-air duct systems where maintaining system pressure and minimizing duct leakage is a priority. The 84RAT9 is sized at 9 inches in diameter to match standard round duct sizing.

This takeoff is suited for residential and light commercial forced-air HVAC applications. It is used where a branch duct must be tapped off a main trunk line or an existing round duct run. The stick-on design is particularly useful in tight spaces or retrofit situations where drilling and fastening are difficult. Licensed HVAC technicians and sheet metal contractors typically install this fitting during new construction ductwork layout or duct modification work.

Key Features

• Airtight construction minimizes air leakage at branch connection points
• Stick-on adhesive backing allows attachment without mechanical fasteners
• 9-inch diameter matches standard round duct sizing
• Round profile for direct connection to round duct pipe
• Designed for faster installation in new construction and retrofit applications

Compatibility

Designed as an OEM-style replacement and new-install fitting for standard 9-inch round duct systems in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Shut down the air handling system and relieve system pressure before cutting into any existing duct. Ensure the mating duct surface is clean, dry, and free of dust or grease before applying the adhesive backing for proper seal integrity. Local mechanical codes, including applicable SMACNA standards, may require additional mastic or foil tape over the joint.
