Southwark Metal 58_8X7 Pipe Reducer 8x7 Inch

Product Description

The SOUTHWARK METAL 58_8X7 is a 3-piece sheet metal pipe reducer used to transition between 8-inch and 7-inch round duct sections in forced-air HVAC distribution systems. Constructed from hot dip galvanized steel, this reducer resists corrosion in both conditioned and unconditioned spaces. The no-crimp design means the ends arrive without a factory-applied bead, giving the installer control over fitting connections during assembly. Licensed HVAC technicians and sheet metal workers install this fitting as part of duct trunk-and-branch layouts in residential and light commercial applications.

This reducer is suited for round duct systems where airflow must be stepped down from an 8-inch main or branch to a 7-inch run. It is commonly installed in residential forced-air systems, supply trunk reductions, and branch takeoff transitions. The 3-piece construction allows the fitting to maintain consistent geometry across the transition, supporting balanced static pressure in the duct system. Installation meets ACCA and SMACNA standards for sheet metal ductwork fabrication and assembly.

Key Features

• Transitions from 8-inch diameter to 7-inch diameter round duct
• Hot dip galvanized steel construction for corrosion resistance
• 3-piece design maintains consistent taper geometry
• No-crimp ends give the installer flexibility during field connection
• Meets ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 8-inch to 7-inch round sheet metal duct systems assembled to SMACNA and ACCA standards.

Installation Notes

Installation is performed by a licensed HVAC technician or journeyman sheet metal worker. Power down the air handling unit before working inside the duct system. Secure connections with sheet metal screws and seal all joints with UL 181-rated mastic or foil tape per SMACNA guidelines. No-crimp ends should be field-beaded or connected using appropriate slip couplings to ensure a secure, airtight fit.
