Southwark Metal SL60-26GA_4IN Round Duct Pipe 4 in 26 Gauge

Product Description

The SOUTHWARK METAL SL60-26GA_4IN is a hot dip galvanized steel round sheet metal pipe designed for low-pressure HVAC duct distribution systems. Fabricated at 26 gauge and sized at 4 inches in diameter with a 60-inch length, this pipe serves as a primary straight-run duct section in forced-air heating and cooling systems. The snap-lock seam construction allows field assembly without separate fasteners, speeding up rough-in work on residential and light commercial projects. HVAC sheet metal mechanics and duct installers are the primary trade users for this component.

This round pipe is used in residential and light commercial forced-air duct systems where a 4-inch diameter branch or trunk run is required. It is well suited for supply or return air branch runs extending from plenums, duct collars, or fittings. At 60 inches per section, fewer joints are needed on longer straight runs, reducing potential leak points. Applications span new construction and retrofit installations where SMACNA and ACCA duct fabrication standards are required by contract or local code.

Key Features

• Hot dip galvanized steel construction resists corrosion in conditioned-air environments
• 26-gauge material thickness meets SMACNA and ACCA standards for low-pressure round duct
• Snap-lock seam allows quick field assembly without additional fasteners
• 4-inch diameter fits standard residential branch-duct collars, boots, and fittings
• 60-inch section length reduces joint count on straight duct runs
• Complies with ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style replacement and new-construction component for 4-inch diameter round duct systems fabricated to SMACNA and ACCA standards in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal mechanic. Power down the air handling system before connecting new duct sections, and follow SMACNA duct construction standards and local mechanical code for sealing, support spacing, and joint fastening. Snap-lock seams should be fully engaged before securing with sheet metal screws and sealing all joints with UL 181-listed mastic or foil tape as required by code. Do not compress or deform the pipe during handling, as out-of-round sections will not seat correctly in fittings.
