Southwark Metal 58_5X3 Sheet Metal Pipe Reducer 5x3 in

Product Description

The SOUTHWARK METAL 58_5X3 is a 3-piece sheet metal pipe reducer designed to transition round duct from a 5-inch diameter down to a 3-inch diameter. Constructed from hot dip galvanized steel, this reducer resists corrosion in both supply and return air applications. The no-crimp design means the larger end ships without a factory crimp, allowing the installer to fit or crimp in the field as needed. HVAC technicians and sheet metal contractors use this fitting to reduce trunk line branches or connect differing duct sizes within residential and light commercial forced-air systems. It meets ACCA and SMACNA standards for ductwork fabrication.

This reducer fits standard round duct systems where a size transition is required between a 5-inch and 3-inch run. Typical installations include branch takeoffs from a main trunk, connections to register boots, or transition points between duct sections of different diameters. The 3-piece construction allows for consistent fit and secure assembly. It is suited for residential forced-air heating and cooling systems and light commercial applications where SMACNA-compliant fittings are specified.

Key Features

• Transitions 5-inch diameter duct down to 3-inch diameter in a single fitting
• Hot dip galvanized steel construction for corrosion resistance
• No-crimp larger end for field fitting flexibility
• 3-piece construction for consistent shape and secure assembly
• Meets ACCA and SMACNA ductwork fabrication standards

Compatibility

Designed as an OEM-style replacement and new-installation fitting for standard round galvanized duct systems requiring a 5-inch to 3-inch reducer transition.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal contractors. Power down the air handling unit and close the system before cutting into existing ductwork. Secure all joints with sheet metal screws and seal with mastic or UL 181-listed tape per SMACNA guidelines. The no-crimp end should be field-crimped with appropriate sheet metal crimping tools before inserting into the adjoining duct section.
