Southwark Metal 58_14X12 Sheet Metal Pipe Reducer 14x12

Product Description

The SOUTHWARK METAL 58_14X12 is a 3-piece sheet metal pipe reducer designed to transition round ductwork from a 14-inch diameter down to a 12-inch diameter. Fabricated from hot dip galvanized steel, this reducer resists corrosion in both exposed and concealed duct installations. It ships without a crimped end, giving the installer flexibility to field-crimp as needed for the specific connection. HVAC mechanics and sheet metal workers install this fitting in forced-air residential and light commercial systems where airflow must be stepped down between duct sections.

This reducer is suited for low-pressure supply and return trunk-to-branch transitions in ducted HVAC systems. The 3-piece construction provides a rigid, dimensional fitting that holds its shape during installation. It is built to meet ACCA and SMACNA standards, making it appropriate for new construction, renovation, and replacement ductwork projects where code-compliant fittings are required.

Key Features

• Transitions round duct from 14 inches to 12 inches in a single fitting
• Hot dip galvanized steel construction for corrosion resistance
• 3-piece design provides structural rigidity and dimensional accuracy
• No factory crimp — field crimp as required for the connection type
• Meets ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style replacement or new-installation fitting for residential and light commercial round duct systems requiring a 14-inch to 12-inch concentric reduction.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal workers. Turn off the air handling unit and lock out the system before cutting into existing ductwork. Secure the fitting with sheet metal screws and seal all joints with UL 181-rated mastic or foil tape per SMACNA guidelines. Field-crimp the appropriate end before inserting into the adjoining duct section if a slip connection is required.
