Imperial GV0286-C 4 in Adjustable 30GA Galvanized Furnace Elbow

Product Description

The IMPERIAL MFG GROUP USA INC GV0286-C is a 4-inch adjustable 30-gauge galvanized steel furnace elbow designed for HVAC duct fabrication and furnace flue or supply-air connections. This 90-degree elbow allows field adjustment to fit varying installation angles, reducing the need for multiple fixed fittings on the job. The 30-gauge galvanized construction provides corrosion resistance suited for typical residential and light commercial duct systems. HVAC installers and sheet metal mechanics use this fitting to make direction changes in rectangular or round duct runs connected to gas furnaces and air handlers.

This elbow is used in residential and light commercial HVAC installations where a 4-inch duct run requires a 90-degree directional change. It is appropriate for supply-air, return-air, and furnace collar transitions in forced-air heating systems. The adjustable design is useful in tight mechanical rooms or attic installations where fixed-angle fittings create alignment problems. It ships in a package quantity of 8 units, making it practical for contractors stocking service vehicles or completing multi-unit jobs.

Key Features

• Adjustable 90-degree design allows field-angle tuning without cutting or fabricating custom fittings
• 4-inch diameter fits standard residential furnace collars and duct connections
• 30-gauge galvanized steel construction resists corrosion in conditioned and unconditioned spaces
• Packaged in quantities of 8 for efficient contractor stocking
• Suitable for forced-air furnace and air handler duct transitions

Compatibility

Designed as an OEM-style replacement and standard-fit component for 4-inch galvanized duct systems in residential and light commercial forced-air HVAC installations.

Installation Notes

Installation is performed by licensed HVAC technicians or sheet metal mechanics following local mechanical codes and SMACNA duct construction standards. Power down the furnace or air handler at the disconnect before modifying any duct connections. Secure the elbow with sheet metal screws and seal all joints with UL-listed duct tape or mastic sealant to maintain system efficiency and prevent air leakage. Do not exceed the gauge rating by applying excessive force when adjusting the elbow angle.
