Southwark Metal 90-30GA_3IN Round Duct Elbow 90 Deg 3 in

Product Description

The SOUTHWARK METAL 90-30GA_3IN is a 90-degree round sheet metal duct elbow fabricated from hot-dip galvanized steel at 30 gauge thickness. Designed for low-pressure residential and light commercial HVAC ductwork, it provides a clean 90-degree directional change in a 3-inch round duct system. The hot-dip galvanized finish delivers corrosion resistance suited for supply and return air applications. This fitting is manufactured to meet ACCA and SMACNA standards, making it appropriate for code-compliant duct installations. HVAC installers and sheet metal contractors rely on this type of fitting for trunk-and-branch and radial duct layouts where precise airflow routing is required.

This elbow is used in residential forced-air heating and cooling systems, as well as light commercial HVAC applications requiring 3-inch round duct transitions. Typical install scenarios include branch takeoffs from main trunk lines, transitions around structural obstacles, and supply register drops. The 3-inch diameter on both the inlet and outlet makes it a straight-size fitting with no reduction. It conforms to ACCA and SMACNA fabrication and dimensional standards, which are commonly referenced in mechanical permit drawings and duct design specifications.

Key Features

• 90-degree turn angle for standard directional changes in round duct systems
• Hot-dip galvanized steel construction for corrosion resistance in air distribution applications
• 30 gauge material thickness suitable for low-pressure residential and light commercial ductwork
• 3-inch inlet and 3-inch outlet diameter — no reduction, straight-size fitting
• Meets ACCA and SMACNA applicable standards for duct fabrication and installation

Compatibility

Designed as an OEM-style replacement and new-construction fitting for 3-inch round galvanized steel duct systems in residential and light commercial forced-air HVAC installations conforming to ACCA and SMACNA standards.

Installation Notes

Installation is performed by licensed HVAC technicians or sheet metal contractors. Power down the air handling unit before making any duct connections or modifications. Secure the elbow to adjoining duct sections using sheet metal screws and seal all joints with UL 181-rated duct mastic or approved metal foil tape per SMACNA guidelines. Avoid relying on duct tape alone, as it does not meet most mechanical code requirements for duct sealing.
