Southwark Metal 78_14X12X12 Duct Wye Branch 14x12x12

Product Description

The SOUTHWARK METAL 78_14X12X12 is a round sheet metal duct wye branch fitting used to split a single trunk duct into two branch runs in residential and light commercial HVAC duct systems. Constructed from hot-dipped galvanized steel, it provides corrosion resistance suitable for supply and return air applications. The fitting measures 14 inches on the main trunk with two 12-inch branch outlets. HVAC installers and sheet metal contractors use this type of wye branch when airflow must be divided at a junction point while maintaining round duct continuity throughout the system.

This wye branch fitting is suited for forced-air heating and cooling distribution systems where round ductwork is specified. It is a common component in new construction and retrofit installations that follow ACCA and SMACNA duct fabrication and performance standards. The 14-inch by 12-inch by 12-inch configuration handles trunk-to-branch transitions in systems where balanced airflow across two zones or outlets is required. Sheet metal contractors and HVAC mechanics install this fitting during rough-in or duct modification work.

Key Features

• Hot-dipped galvanized steel construction for corrosion resistance in air distribution environments
• Round duct configuration with 14-inch main and dual 12-inch branch outlets
• Meets ACCA and SMACNA applicable standards for duct fittings
• Wye branch geometry supports balanced airflow splitting versus abrupt tee fittings
• Compatible with standard round spiral and snap-lock duct systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for round sheet metal duct systems requiring a 14-inch by 12-inch by 12-inch wye branch junction, fabricated to ACCA and SMACNA standards.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Shut down the air handling unit and confirm the system is de-energized before cutting into or modifying existing ductwork. Seal all joints with UL 181-listed duct sealant or approved metal foil tape per local mechanical code requirements. Support the fitting independently per SMACNA hanger spacing guidelines to prevent stress on adjacent duct connections.
