Southwark Metal 90-26GA_4IN Round Duct Elbow 90 Deg 4 in 26 Ga

Product Description

The SOUTHWARK METAL 90-26GA_4IN is a round sheet metal duct elbow designed for 90-degree directional changes in low-pressure HVAC duct systems. Fabricated from hot dip galvanized steel at 26 gauge, this fitting delivers corrosion resistance and structural rigidity expected in commercial and residential duct installations. The elbow measures 4 inches in diameter on both the inlet and outlet, making it a straight-size fitting with no transition. HVAC installers and sheet metal contractors use this component when routing round duct through tight spaces or when a hard 90-degree turn is required in a supply or return air trunk system.

This elbow is suited for residential and light commercial forced-air HVAC applications where round galvanized ductwork is the specified system type. It fits standard 4-inch round duct collar connections and is appropriate for use in supply branches, exhaust runs, and ventilation layouts that require a 90-degree change of direction. The hot dip galvanized finish makes it a reliable choice in unconditioned spaces such as attics, crawlspaces, and mechanical rooms where moisture exposure is a consideration.

Key Features

• 90-degree angle provides a hard directional change for round duct runs
• Hot dip galvanized steel construction resists corrosion in unconditioned spaces
• 26 gauge material thickness meets standard ACCA and SMACNA fabrication requirements
• 4-inch diameter on both ends — no transition, no reducer required
• Round profile compatible with standard round duct collars and snap-lock fittings

Compatibility

Designed as an OEM-style replacement and new-installation fitting for standard 4-inch round galvanized duct systems in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal contractors. Power down the air handling equipment before connecting or modifying any duct section. Secure the elbow with sheet metal screws and seal all joints with UL 181-listed duct tape or mastic sealant per SMACNA and local mechanical code requirements. Do not use this fitting in high-pressure or high-velocity duct systems beyond its design rating.
