Imperial Mfg Group Usa Inc GV1359 Taper Increaser 6x7 24GA

Product Description

The IMPERIAL MFG GROUP USA INC GV1359 is a 24-gauge galvanized steel taper increaser designed to transition round duct from a 6-inch diameter to a 7-inch diameter. The large end is factory-crimped for straightforward slip-fit connection into the next duct section. This fitting is a standard component in residential and light commercial HVAC sheet metal ductwork, typically installed by HVAC sheet metal mechanics during new construction or duct modification work. The galvanized steel construction resists corrosion and holds up in both supply and return air applications.

This taper increaser is used when a duct run requires an upsized transition between two round duct sections of differing diameters. The 6-inch small end connects to the upstream duct, and the 7-inch crimped large end fits into the downstream section. It is suited for residential forced-air systems and light commercial HVAC installations where a smooth, gradual diameter change is needed to manage airflow and static pressure through the duct system.

Key Features

• 6-inch to 7-inch round duct transition for upsizing duct diameter
• 24-gauge galvanized steel construction for corrosion resistance
• Large end factory-crimped for slip-fit installation
• Tapered profile supports smooth airflow transition and reduced turbulence
• Sold in a package quantity of 12 units

Compatibility

Designed as an OEM-style replacement and standard fitting for round galvanized ductwork systems requiring a 6-inch to 7-inch increaser transition.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal mechanic. Power down the air handling equipment before making any duct connections. Secure the fitting with sheet metal screws and seal all joints with UL-listed duct sealant or metal foil tape in accordance with local mechanical codes. Do not use standard cloth-backed duct tape as a primary air seal.
