Imperial GV0285-C 4 Inch 28GA Adjustable Furnace Elbow

Product Description

The IMPERIAL MFG GROUP USA INC GV0285-C is a 4-inch adjustable 28-gauge galvanized steel furnace elbow designed for residential and light commercial HVAC duct systems. This 90-degree elbow connects and redirects rectangular or round supply and return air runs in forced-air furnace installations. The 28-gauge galvanized construction resists corrosion and holds shape under the temperature cycling typical of gas and electric furnace applications. HVAC technicians and sheet metal installers use this fitting to complete trunk-line transitions and branch takeoffs where a fixed elbow will not fit. The adjustable design allows field workers to fine-tune the angle for a flush, airtight connection without custom fabrication on the job site.

This elbow is suited for new furnace installations, duct retrofits, and system modifications in residential homes and small commercial buildings. It is installed in forced-air heating and cooling distribution systems where a 4-inch galvanized fitting is required to make a 90-degree directional change. The package quantity of 8 pieces per unit makes this fitting practical for contractors stocking supplies for multiple jobs or multi-zone duct layouts.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal installer in accordance with local mechanical codes and SMACNA duct construction standards. Power down the furnace and set the thermostat to off before working on any connected ductwork. Seal all joints with UL-listed duct mastic or metal-backed tape to meet air-tightness requirements. Do not use general-purpose cloth duct tape as a permanent seal on galvanized sheet metal fittings.
