Southwark Metal 58_10X9 Sheet Metal Pipe Reducer 10x9

Product Description

The SOUTHWARK METAL 58_10X9 is a 3-piece sheet metal pipe reducer designed to transition round duct from a 10-inch diameter down to a 9-inch diameter in forced-air HVAC systems. Fabricated from hot dip galvanized steel, this reducer delivers corrosion resistance suited for both supply and return duct applications. The no-crimp design means the fitting ships without a crimped end, allowing the installer to orient and prepare the connection as the job requires. HVAC sheet metal mechanics and ductwork installers are the primary trades working with this fitting on residential and light commercial air distribution systems.

This reducer is used where a main trunk or branch run steps down one pipe size, a common scenario when balancing airflow across multiple zones or transitioning between duct sections of differing diameters. It is appropriate for low-pressure forced-air supply and return duct assemblies in residential new construction, renovation, and equipment replacement work. The fitting meets ACCA and SMACNA fabrication and installation standards, making it suitable for jobs where code-compliant ductwork documentation is required.

Key Features

• Transitions 10-inch diameter duct to 9-inch diameter duct in a single fitting
• Hot dip galvanized steel construction provides corrosion resistance for long service life
• 3-piece construction for consistent dimensional fit across the reducer body
• No-crimp end gives the installer flexibility to prepare the connection on site
• Meets ACCA and SMACNA applicable standards for forced-air duct systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for round sheet metal duct systems using 10-inch and 9-inch diameter pipe sections in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal mechanics. Power down the air handling unit and close the system before cutting into or modifying any duct section. Secure the reducer with sheet metal screws and seal all joints with mastic sealant or listed foil tape per SMACNA guidelines and local mechanical code requirements. Do not use standard duct tape as a primary sealant on pressure-tested duct systems.
