Southwark Metal 78161414 Wye Branch 16x14x14 Duct Fitting

Product Description

The SOUTHWARK METAL 78161414 is a sheet metal wye branch fitting designed to split a single duct run into two equal branch legs without significant loss of airflow or air velocity. Sized at 16 inches on the trunk inlet by 14 inches on each of the two outlet legs, this fitting maintains balanced static pressure across both branches. It is used in low-pressure forced-air HVAC ductwork systems and is installed by licensed HVAC technicians or sheet metal contractors during new construction or system modification work.

This wye branch is suited for residential and light commercial supply or return air duct systems where a trunk line must be divided into two equal runs. The equal 14-inch outlets support symmetrical airflow distribution, making this fitting appropriate for systems that require balanced branch velocities rather than a directional offset. The fitting ships as a single unit and is field-connected using standard sheet metal fasteners and duct sealant or tape per local mechanical code requirements.

Key Features

• Equal dual-outlet design splits airflow evenly across both 14-inch branch legs
• 16-inch trunk inlet accommodates larger main duct runs common in commercial and larger residential systems
• Sheet metal construction provides rigid, durable performance in forced-air duct systems
• Wye geometry preserves air velocity better than abrupt tee fittings in balanced-flow applications
• Sold individually, allowing targeted replacement or single-point system expansion

Compatibility

Comparable to Snappy Item 720-161414. Designed as an OEM-style sheet metal wye branch fitting for use in standard low-pressure forced-air HVAC duct systems accepting 16-inch trunk and 14-inch branch connections.

Installation Notes

Installation should be performed by a qualified HVAC technician or licensed sheet metal contractor in accordance with SMACNA duct construction standards and applicable local mechanical codes. Shut down and lock out the air handling unit before cutting into or modifying any duct section. Secure the fitting with sheet metal screws and seal all joints with UL-listed duct sealant or approved foil tape to prevent air leakage. Avoid sharp bends or unsupported duct connections directly at the wye outlet collars, as this can create turbulence and reduce system efficiency.
