Southwark Metal 58_10X7 Sheet Metal Pipe Reducer 10x7

Product Description

The SOUTHWARK METAL 58_10X7 is a 3-piece sheet metal pipe reducer designed to transition round ductwork from a 10-inch diameter down to a 7-inch diameter. Constructed from hot dip galvanized steel, it delivers corrosion resistance suited for both supply and return air duct systems. The no-crimp design means the installer is responsible for field-fabricated connections at each end. This fitting is built to ACCA and SMACNA standards, making it a code-appropriate choice for residential and light commercial HVAC duct installations. HVAC sheet metal mechanics and duct fabricators are the primary installers of this component.

This reducer fits into round duct systems where airflow must be stepped down between two different duct diameters. Typical applications include trunk-to-branch transitions, air handler supply plenums, and inline duct reductions in forced-air heating and cooling systems. The 3-piece construction is standard for larger-diameter reducers and provides consistent geometry for a secure duct connection. It is appropriate for low-pressure residential and commercial HVAC ductwork where SMACNA and ACCA guidelines govern fabrication and installation.

Key Features

• Transitions round duct from 10 inches to 7 inches in a single fitting
• Hot dip galvanized steel construction for corrosion resistance in duct environments
• 3-piece design standard for larger-diameter round duct reducers
• No crimp supplied — field connection method applied by installer
• Meets ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style replacement and standard fabrication fitting for round duct systems requiring a 10-inch to 7-inch diameter reduction 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 verify the system is de-energized before working in the duct system. Secure all joints with approved sheet metal screws and seal with mastic or UL 181-listed tape in accordance with SMACNA duct construction standards. Follow local mechanical codes for duct support and clearance requirements.
