Southwark Metal 90-30GA_9IN Round Duct Elbow 9 in 30 Gauge

Product Description

The SOUTHWARK METAL 90-30GA_9IN is a round 90-degree sheet metal duct elbow fabricated from hot dip galvanized steel at 30 gauge. It is designed for use in low-pressure residential and light commercial HVAC duct systems where a 90-degree directional change is needed in a round duct run. Both the inlet and outlet diameters measure 9 inches, making this a straight-size elbow with no transition. HVAC sheet metal contractors and ductwork installers use this fitting when assembling supply or return air distribution systems that conform to ACCA and SMACNA standards.

This elbow fits into round spiral or snap-lock duct systems in forced-air heating and cooling applications. It is commonly installed in residential new construction and retrofit ductwork where space constraints require a 90-degree turn in a 9-inch round duct line. The galvanized steel construction resists corrosion in conditioned-air environments, including installations in attics, crawlspaces, and mechanical rooms. Its compliance with ACCA and SMACNA standards makes it appropriate for permitted commercial and residential HVAC projects.

Key Features

• 90-degree angle provides a full directional change in round duct runs
• 9-inch inlet and 9-inch outlet diameters — no transition, straight-size fitting
• 30-gauge hot dip galvanized steel construction for corrosion resistance
• Meets ACCA and SMACNA applicable standards for HVAC ductwork
• Round profile compatible with standard spiral and snap-lock round duct systems

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 9-inch round duct systems built to ACCA and SMACNA standards in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation is typically performed by licensed sheet metal contractors or HVAC technicians. Shut down and lock out the air handling system before connecting or disconnecting duct fittings. Secure the elbow to adjoining duct sections using sheet metal screws and seal all joints with UL 181-rated mastic or foil tape in accordance with local mechanical codes and SMACNA guidelines. Do not use standard duct tape as a primary sealant.
