Air Flow Products 86F8 Full Flow Tee 8x8x8

Product Description

The AIR FLOW PRODUCTS 86F8 is a full flow tee fitting designed for duct systems where maintaining maximum airflow through each branch is critical. Unlike standard tees that restrict flow at the branch takeoff, the full flow design minimizes turbulence and pressure drop across all three ports. At 8x8x8 inches, all three openings share the same cross-sectional dimension, making this fitting well suited for balanced distribution in trunk-and-branch ductwork layouts. HVAC technicians and sheet metal contractors select this type of fitting when system design calls for equal static pressure across branches.

This tee is used in residential and light commercial HVAC duct installations where airflow balance is a design priority. It fits inline within rectangular duct runs requiring a same-size tee connection at the main trunk or a branch split. The 8x8x8 configuration is common in medium-capacity supply or return air applications. Installation typically takes place during new construction rough-in or duct renovation projects handled by licensed HVAC technicians or sheet metal workers.

Key Features

• Full flow design reduces pressure drop and turbulence at the branch junction
• Equal 8x8x8 opening dimensions allow balanced airflow across all three ports
• Uniform port sizing simplifies duct layout in balanced distribution systems
• Sized for medium-capacity rectangular duct applications

Compatibility

Designed as an OEM-style fitting for use in standard rectangular duct systems requiring an 8-inch by 8-inch by 8-inch full flow tee connection.

Installation Notes

Installation of this tee fitting is typically performed by a licensed HVAC technician or certified sheet metal worker. Power down the air handling unit and verify the system is de-energized before cutting into any existing duct section. Secure all connections with approved sheet metal screws and seal joints with UL-listed duct sealant or metal-backed tape per local mechanical code requirements. Verify airflow direction and branch orientation against the duct design drawings before final fastening.
