The Southwark Metal 720-141212 is a galvanized steel wye branch fitting designed for sheet metal ductwork installations. It is used to split a single duct run into two equal branches, maintaining balanced airflow and air velocity through both legs of the system. HVAC technicians and sheet metal installers rely on wye branch fittings like this one to create efficient duct layouts in residential and light commercial applications. Unlike a standard tee fitting, a wye branch uses angled transitions that reduce turbulence and pressure drop, helping the system move conditioned air more effectively to each zone. This fitting measures 14 inches on the main trunk inlet and 12 inches on each of the two branch outlets, making it suitable for medium to larger duct systems where maintaining volume and velocity across branches is a priority. The 720-141212 is fabricated from 28 gauge galvanized steel, which provides corrosion resistance and structural rigidity for long-term performance in both supply and return air applications. The galvanized coating protects against moisture and rust, which is especially important in installations where condensation or humidity may be present. This fitting is manufactured in the USA and sold as a single unit. It is comparable to Southwark Metal item 78141212 and Snappy item 720-141212, making it a reliable cross-reference option for contractors sourcing replacement or new-construction duct components. The fitting carries a Prop 65 designation. At approximately 3.5 pounds, it is manageable for single-technician handling during installation. This wye branch is a standard component in forced-air HVAC duct systems and is compatible with rectangular sheet metal ductwork of matching dimensions.
The Southwark Metal 720-141212 wye branch fitting provides a durable, galvanized steel solution for splitting ductwork into two equal branches while preserving airflow efficiency. It is a trusted component for HVAC installers working on residential and light commercial forced-air systems.
