Air Flow Products 86F20 Full Flow Tee 20x20x20

Product Description

The AIR FLOW PRODUCTS 86F20 is a full flow tee fitting designed for duct and air distribution systems. This tee maintains consistent airflow through all three openings, minimizing turbulence and pressure drop at the branch connection. The 20x20x20-inch configuration makes it suitable for larger trunk and branch duct runs in commercial and residential HVAC applications. HVAC installers and sheet metal contractors select this tee where balanced airflow and low resistance at the junction are required.

The 86F20 is used in forced-air HVAC duct systems where a main duct run must split into a branch of equal size. The 20-inch opening on all three ports suits larger air handler outputs and commercial rooftop unit distribution. It is typically installed in supply or return duct trunk lines during new construction or duct replacement projects.

Key Features

• Full flow design reduces pressure drop and turbulence at the tee junction
• Equal 20-inch openings on all three ports for balanced airflow
• Suitable for supply and return duct applications
• Consistent cross-section throughout supports efficient air distribution

Compatibility

Designed as an OEM-style replacement or new-install fitting for forced-air duct systems using 20-inch round or equivalent duct connections.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal contractors. Power down the air handler and close the system before cutting into existing ductwork. Seal all joints with approved duct mastic or UL 181-listed tape in accordance with local mechanical codes. Secure the fitting with sheet metal screws at each connection point before applying sealant.
