Air Flow Products 86F3 Full Flow Tee 3 Inch

Product Description

The AIR FLOW PRODUCTS 86F3 is a full flow tee fitting designed for fluid or air distribution systems requiring a 3-inch by 3-inch by 3-inch configuration. Full flow tees maintain consistent bore diameter through all three ports, minimizing pressure drop and turbulence at the branch point. This fitting is suited for HVAC, plumbing, and mechanical systems where maintaining flow velocity through the tee is a priority. Installation is typically performed by licensed plumbers, HVAC technicians, or pipefitters working on trunk and branch distribution systems.

The 86F3 is sized at 3 inches on all three ports, making it a straight-run branch fitting for systems where equal flow distribution or balanced branching is required. It is commonly used in residential and light commercial mechanical installations where a low-restriction branch connection is needed at a main run of pipe or duct.

Key Features

• Full flow bore through all three ports minimizes pressure drop at branch connections
• Equal 3-inch port sizing on all three openings for balanced flow distribution
• Suitable for trunk-and-branch HVAC, plumbing, or mechanical piping layouts
• Consistent bore design reduces turbulence compared to standard reducing tees

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3-inch piping or duct systems in residential and light commercial HVAC and plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or pipefitter familiar with applicable codes such as the IPC or IFGC. Shut off system pressure and isolate the line section before cutting in or connecting the tee. Verify that all three port connections are properly sealed and supported before returning the system to service. Do not overtighten threaded connections or use incompatible joining methods for the pipe or duct material being used.
