Southwark Metal 581612 3-piece Duct Reducer 16 Inches X 12 Inches No Crimp Galvanized Steel

Product Description

The Southwark Metal 581612 is a 3-piece duct reducer designed to transition round ductwork from 16 inches down to 12 inches. It is built for HVAC installers, sheet metal contractors, and mechanical trades professionals who need a reliable, leak-resistant connection between different duct diameters. This reducer features a no-crimp design, which means the ends do not have a machine-crimped bead. That makes it compatible with duct runs where a smooth, uncrimped fitting is required for a proper connection or overlap fit. The no-crimp style is commonly used when joining to fittings or collars that already have a crimp, keeping the overall assembly clean and secure. The 581612 is manufactured from hot-dipped galvanized steel meeting ASTM A653 CS Type B standards. This galvanized coating provides strong corrosion resistance, making the reducer suitable for both supply and return air systems in residential and light commercial HVAC applications. The 28-gauge steel construction balances strength with workability, allowing field techs to make adjustments when needed without excessive effort. At approximately 2.2 pounds, this fitting is lightweight enough for single-person installation. The overall length measures 16 inches, with a width of 16 inches at the large end, transitioning to 12 inches at the small end. The height is 8.25 inches. This reducer ships as an individual unit and is made in the USA. It carries a Prop 65 designation. HVAC professionals looking for round duct reducers, galvanized sheet metal fittings, or no-crimp duct transitions will find this fitting meets standard commercial and residential ductwork specifications.
