Imperial GV0782-A 6x4 in Galvanized Taper Reducer 30 Ga

Product Description

The IMPERIAL MFG GROUP USA INC GV0782-A is a galvanized steel taper reducer and increaser designed for round duct transitions in forced-air HVAC systems. It steps down from a 6-inch diameter to a 4-inch diameter and is fabricated from 30-gauge galvanized sheet metal. The no-crimp end design allows for a clean slip fit into standard duct fittings without requiring a crimping step. This fitting is a standard component in residential and light commercial duct fabrication and is typically installed by HVAC technicians and sheet metal mechanics during system installation or duct modification work.

This reducer and increaser is suited for residential forced-air systems where duct transitions between main trunk lines and branch runs are required. It handles airflow direction in either orientation, functioning as a reducer when installed from larger to smaller diameter or as an increaser in the reverse direction. The fitting is sold in a package quantity of 12 units, making it practical for contractors stocking fittings for multiple jobs or larger duct system builds.

Key Features

• Tapered profile transitions between 6-inch and 4-inch round duct diameters
• 30-gauge galvanized steel construction for corrosion resistance in conditioned air applications
• No-crimp end design allows direct slip-fit connection without additional prep
• Bidirectional use as both a reducer and an increaser depending on install orientation
• Sold in a package of 12 units for job-site convenience

Compatibility

Designed as an OEM-style galvanized duct fitting compatible with standard 6-inch and 4-inch round duct systems used in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation is performed by licensed HVAC technicians or sheet metal mechanics. Power down the air handling unit and verify the system is de-energized before modifying any ductwork. Secure the fitting with sheet metal screws and seal all joints with UL 181-listed duct tape or mastic sealant per local mechanical code requirements. Use aviation snips and appropriate hand tools when cutting or adjusting adjacent duct sections.
