Southwark Metal 54-24GA_18IN Steel Pipe Tee 18in 24 Gauge

Product Description

The Southwark Metal 54-24GA_18IN is an 18 x 18 x 18 inch galvanized steel pipe tee fabricated from hot-dip galvanized steel at 24 gauge wall thickness. It is designed for use in low-pressure supply and return air duct systems where a straight-through branch connection is required. The hot-dip galvanization process provides corrosion resistance suited to mechanical room and attic installations. This fitting is installed by sheet metal workers and HVAC technicians as part of residential or light commercial duct distribution systems.

This tee fitting is used in rectangular or round duct branch connections within forced-air HVAC systems. Its equal 18-inch dimensions on all three openings make it appropriate for main trunk splits and equal-flow branch configurations. It conforms to ACCA and SMACNA standards, making it suitable for systems where duct construction specifications must meet those guidelines. Typical installations include air handler distribution trunks in residential new construction and light commercial retrofit applications.

Key Features

• Hot-dip galvanized steel construction for corrosion resistance in mechanical and attic environments
• 24 gauge wall thickness meeting SMACNA and ACCA fabrication standards
• Equal 18 x 18 x 18 inch opening configuration for balanced branch connections
• ACCA and SMACNA compliant for use in code-referenced duct installations
• Suitable for low-pressure supply and return air duct systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 18-inch rectangular or round duct systems built to ACCA and SMACNA standards in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation should be performed by a licensed sheet metal worker or HVAC technician in accordance with SMACNA duct construction standards and local mechanical codes. Shut down and de-energize the air handling unit before making duct connections. Seal all joints with listed duct sealant or mastic and secure with sheet metal screws per SMACNA guidelines. Do not use this fitting in high-pressure duct systems without verifying gauge and reinforcement requirements for the pressure class.
