Air Flow Products 86F6 Full Flow Tee 6x6x6

Product Description

The AIR FLOW PRODUCTS 86F6 is a full flow tee fitting designed for duct and piping systems where maintaining maximum airflow through the branch connection is critical. Unlike standard tees that restrict flow at the junction, the full flow design preserves cross-sectional area through all three openings. This fitting is sized at 6 x 6 x 6 inches across all ports, making it a symmetrical tee suitable for balanced distribution runs. HVAC technicians and sheet metal contractors install this type of fitting during system fabrication or retrofit work where branch losses need to be minimized.

The 86F6 is suited for residential and light commercial HVAC duct systems, particularly in supply trunk line configurations where airflow balancing across multiple zones is a priority. The equal 6-inch port sizing allows it to serve as a main-to-branch transition without reducing duct diameter at any leg of the connection. It is also appropriate for ventilation and exhaust applications where consistent flow rates across all branches are required.

Key Features

• Full flow design maintains airflow volume through all three ports
• Symmetrical 6 x 6 x 6 inch configuration supports balanced branch distribution
• Equal port sizing eliminates the need for reducers at the tee junction
• Suitable for supply trunk, return, ventilation, and exhaust duct runs

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 6-inch round duct systems in residential and light commercial HVAC, ventilation, and exhaust applications.

Installation Notes

This fitting is typically installed by licensed HVAC technicians or sheet metal contractors during duct fabrication or system modification. Power down the air handling unit and verify the system is de-energized before working on connected ductwork. Secure all connections with approved sheet metal screws and seal joints with UL-listed mastic or foil tape in accordance with local mechanical codes and SMACNA standards. Support the fitting and connected duct sections per applicable code requirements to prevent stress on joints.
