Imperial GV0284-C 4 in Adjustable 26GA Galvanized Furnace Elbow

Product Description

The IMPERIAL MFG GROUP USA INC GV0284-C is a 4-inch adjustable 90-degree furnace elbow fabricated from 26-gauge galvanized steel. It is used in residential and light commercial HVAC duct systems to redirect airflow at a 90-degree angle within furnace supply or return plenums. The galvanized finish provides corrosion resistance in typical indoor duct environments. This fitting is installed by HVAC technicians during new system installations, duct modifications, or service calls requiring duct rerouting. The adjustable design accommodates minor field adjustments without requiring custom fabrication.

This elbow is suited for forced-air furnace duct systems where a 90-degree directional change is needed. It fits into standard 4-inch round duct runs commonly found in residential furnace installations. The 26-gauge galvanized steel construction meets typical sheet metal duct fabrication standards for light-gauge applications. It is sold in packages of 8 units, making it a practical choice for contractors stocking common duct fittings.

Compatibility

Designed as an OEM-style replacement and standard fitting for 4-inch round duct connections in residential and light commercial forced-air furnace systems.

Installation Notes

Installation is performed by licensed HVAC technicians following applicable mechanical codes such as SMACNA duct construction standards. Shut down the furnace and confirm the system is de-energized before beginning any duct work. Secure the elbow using sheet metal screws and seal all joints with UL-listed duct tape or mastic sealant to maintain system efficiency and air tightness. Do not compress or distort the fitting during installation, as this can restrict airflow.
