Southwark Metal SL24-24GA_4IN Galvanized Round Pipe 24GA 4in

Product Description

The SOUTHWARK METAL SL24-24GA_4IN is a 24-gauge hot-dip galvanized steel round pipe section used in low-pressure residential and light commercial HVAC duct systems. Measuring 4 inches in diameter and 24 inches in length, this snap-lock pipe is fabricated to ACCA and SMACNA standards, making it a code-compliant choice for supply and return air distribution. Sheet metal mechanics and HVAC installers use this pipe to build or extend trunk-and-branch ductwork runs in forced-air heating and cooling systems. The hot-dip galvanized finish provides corrosion resistance suited for both conditioned and unconditioned spaces.

This pipe section is a standard component in residential forced-air HVAC installations, including new construction and retrofit duct systems. The snap-lock seam allows for fast field assembly without additional seaming tools, reducing installation time on the job. It is commonly installed in attics, crawlspaces, basements, and mechanical rooms as part of a complete low-pressure galvanized duct system. ACCA and SMACNA compliance makes it appropriate for use in jurisdictions that reference those standards in their mechanical codes.

Key Features

• Hot-dip galvanized steel construction for corrosion resistance in HVAC duct applications
• 24-gauge material thickness meets SMACNA and ACCA standard requirements for low-pressure duct systems
• Snap-lock end type allows fast, tool-free field assembly
• 4-inch diameter fits standard residential duct fittings, collars, and takeoffs
• 24-inch length provides a manageable straight section for layout flexibility

Compatibility

Designed as an OEM-style replacement and new-install component for standard 4-inch round galvanized duct systems built to ACCA and SMACNA specifications.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal mechanic familiar with SMACNA duct construction standards. Power down the air handling unit before making connections to an existing duct system. Snap-lock seams should be fully engaged and all joints sealed with UL 181-rated mastic or metal foil tape per applicable mechanical codes. Support spacing and hangar requirements should follow SMACNA guidelines for round duct.
