Southwark Metal 58_8X5 Sheet Metal Pipe Reducer 8x5 Inch

Product Description

The SOUTHWARK METAL 58_8X5 is a 3-piece sheet metal pipe reducer designed to transition round duct from an 8-inch diameter down to a 5-inch diameter in forced-air HVAC systems. Fabricated from hot dip galvanized steel, this no-crimp reducer provides a secure, corrosion-resistant connection between duct sections of different sizes. The 3-piece construction allows for straightforward field assembly and ensures a tight fit at both ends. Licensed HVAC technicians and sheet metal contractors install this fitting during trunk-and-branch duct system layout, air handler connections, and duct modification work in residential and light commercial applications.

This reducer is suited for residential and light commercial forced-air duct systems where a branch or main trunk line must be stepped down in diameter. It is commonly installed when transitioning from a main trunk to a smaller branch run, or when connecting an air handler outlet to a reduced-size supply duct. The no-crimp design means neither end requires additional crimping before connection, which simplifies installation when working with standard slip-and-drive or connector fittings. Fabrication meets ACCA and SMACNA standards, making it appropriate for systems built to those industry specifications.

Key Features

• Transitions round duct from 8 inches to 5 inches in a single fitting
• Hot dip galvanized steel construction for corrosion resistance in conditioned and unconditioned spaces
• No-crimp ends on both the larger and smaller openings
• 3-piece design supports consistent field assembly and alignment
• Meets ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style replacement or new-installation fitting for round sheet metal duct systems requiring an 8-inch to 5-inch concentric reduction.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal contractors. Power down and lock out the air handling unit before modifying any connected ductwork. Secure all joints with approved sheet metal screws and seal with mastic or UL 181-rated foil tape per SMACNA installation guidelines. Do not over-compress the fitting ends during assembly, as deformation can restrict airflow through the reducer.
