Southwark Metal SL24-26GA_12IN Round Sheet Metal Pipe 26GA 12in

Product Description

The SOUTHWARK METAL SL24-26GA_12IN is a 26-gauge hot-dip galvanized steel round pipe section designed for low-pressure ducted air distribution systems. At 12 inches in diameter and 24 inches in length, it connects inline with other round duct components using a snap-lock seam construction that speeds field assembly without specialized crimping equipment. HVAC installers use this pipe in residential and light commercial supply and return trunk lines where corrosion resistance and dimensional consistency are required. It meets ACCA and SMACNA fabrication standards, making it suitable for permitted duct installations.

This pipe section fits into round duct systems used in forced-air heating and cooling installations. Typical applications include trunk line extensions, branch runouts from round-to-round fittings, and straight runs between transitions or elbows. The 12-inch diameter suits higher-volume supply or return paths in larger residential systems or small commercial air handlers. The 24-inch section length reduces the number of joints required over a given run, which limits leakage points when properly sealed per SMACNA duct sealing guidelines.

Key Features

• Hot-dip galvanized steel construction resists corrosion in humid mechanical room and crawlspace environments
• Snap-lock seam allows fast field assembly without soldering or riveting
• 26-gauge material thickness meets SMACNA standards for low-pressure round duct
• 12-inch diameter accommodates high-volume airflow paths in larger duct systems
• Compliant with ACCA and SMACNA applicable standards for permitted installations

Compatibility

Designed as an OEM-style round duct pipe section compatible with standard 12-inch diameter round duct fittings, collars, and trunk connections fabricated to SMACNA round duct dimensional standards.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal mechanic familiar with SMACNA duct construction standards. Power down the air handling unit and verify the system is de-energized before cutting into or extending existing ductwork. Joints should be sealed with UL 181-listed mastic or foil tape per local mechanical code requirements. Avoid using this pipe section as structural support for other system components without independent hangers rated for the load.
