Imperial Mfg GV0289-C 5 in 26GA Adjustable Furnace Elbow

Product Description

The IMPERIAL MFG GROUP USA INC GV0289-C is a 5-inch adjustable 90-degree galvanized furnace elbow designed for residential HVAC ductwork and venting applications. Constructed from 26-gauge galvanized steel, this fitting delivers reliable rigidity and corrosion resistance in forced-air heating systems. The adjustable design allows the installer to dial in the exact angle needed to navigate tight spaces and transitions within the duct run, reducing the need for additional fittings. HVAC technicians and sheet metal mechanics reach for this type of elbow when making directional changes in round or oval duct runs connected to furnace supply or return air systems.

This elbow is suited for use in residential forced-air furnace installations where a 90-degree directional change is required in a 5-inch round duct run. The adjustable feature makes it particularly useful in retrofit and replacement scenarios where existing duct layouts do not align perfectly with new equipment. It is commonly installed in attic, crawlspace, basement, and utility closet environments where space constraints make a fixed elbow impractical. Packages include 8 units per case, making it a practical stock item for service fleets or shop inventory.

Key Features

• Adjustable 90-degree angle for flexible duct routing in confined spaces
• 26-gauge galvanized steel construction for corrosion resistance and structural rigidity
• 5-inch diameter fits standard residential round duct systems
• Reduces need for multiple fittings when navigating directional changes
• Packaged 8 units per case for efficient job-site or inventory stocking

Compatibility

Designed as an OEM-style replacement and standard new-installation fitting for 5-inch round duct systems in residential forced-air HVAC applications.

Installation Notes

Installation should be performed by a qualified HVAC technician or licensed sheet metal mechanic in accordance with local mechanical codes and SMACNA duct construction standards. Power down the furnace and confirm the system is de-energized before working on any connected ductwork. Secure all joints with sheet metal screws and seal with UL 181-rated foil tape or mastic sealant to maintain system efficiency and prevent air leakage. Do not overtighten fasteners on 26-gauge material, as this gauge can deform under excessive force.
