Southwark Metal 58_16X14 Pipe Reducer 16x14

Product Description

The SOUTHWARK METAL 58_16X14 is a 3-piece sheet metal pipe reducer used to transition round duct from a 16-inch diameter to a 14-inch diameter in forced-air HVAC distribution systems. Constructed from hot dip galvanized steel, this reducer meets ACCA and SMACNA standards for duct fabrication and installation. It ships without a crimp, making it suited for applications where the installer will apply their own connection method. Licensed sheet metal workers and HVAC technicians install this fitting during new construction and retrofit ductwork projects.

This reducer is used in residential and light commercial HVAC installations where a main trunk or branch run requires a step-down from 16 inches to 14 inches in diameter. It fits into round duct systems where airflow management and proper velocity maintenance across duct transitions are required. The SMACNA and ACCA compliance makes it appropriate for permitted work in jurisdictions that reference those standards.

Key Features

• Transitions round duct from 16-inch to 14-inch diameter in a single fitting
• Hot dip galvanized steel construction resists corrosion in attic, crawlspace, and mechanical room environments
• 3-piece construction for consistent fit across the transition
• No crimp supplied, giving installers flexibility in connection method
• Meets ACCA and SMACNA fabrication standards for permitted ductwork

Compatibility

Designed as an OEM-style replacement and new-installation fitting for round duct systems requiring a concentric step-down reducer between 16-inch and 14-inch diameter sections.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal worker in accordance with SMACNA duct construction standards and applicable local mechanical codes. Shut down the air handling unit and confirm the system is de-energized before working inside the duct system. Secure the reducer to adjacent duct sections using sheet metal screws and seal all joints with UL 181-listed mastic or foil tape as required by code. Do not compress or deform the fitting during installation, as this can affect airflow and fitting integrity.
