Southwark Metal 58_8X6 Sheet Metal Pipe Reducer 8x6 Inch

Product Description

The SOUTHWARK METAL 58_8X6 is a 3-piece sheet metal pipe reducer used to transition duct runs from an 8-inch diameter to a 6-inch diameter. Fabricated from hot dip galvanized steel, it delivers corrosion resistance suitable for residential and light commercial forced-air HVAC ductwork. The reducer ships without a crimp, giving installers the flexibility to field-crimp the appropriate end to match existing duct connections. This fitting is built to ACCA and SMACNA standards, making it a code-appropriate choice for duct systems requiring documented conformance.

This reducer fits standard round sheet metal duct systems where a main trunk or branch line steps down in diameter. Typical applications include supply-side trunk reductions, branch takeoff transitions, and inline diameter changes in residential furnace and air handler duct systems. The 3-piece construction allows for consistent geometry and reliable sealing when mastic or metal tape is applied at the seams. HVAC sheet metal mechanics and ductwork installers are the primary trades working with this fitting.

Key Features

• Transitions duct diameter from 8 inches down to 6 inches in a single fitting
• Hot dip galvanized steel construction provides corrosion resistance for long-term duct service
• No crimp supplied — field crimp as needed to match existing duct configuration
• 3-piece design maintains consistent taper geometry for proper airflow transition
• Meets ACCA and SMACNA applicable standards for duct fabrication and installation

Compatibility

Designed as an OEM-style replacement and standard fitting for round sheet metal duct systems with an 8-inch supply or branch line transitioning to a 6-inch run.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal mechanics. Shut down the air handling system and verify the system is de-energized before modifying any duct section. Seal all seams and joints with UL 181-listed mastic or foil tape per SMACNA duct construction standards. Field-crimp the appropriate end before inserting into the adjacent duct section to ensure a secure, low-leakage connection.
