Imperial Mfg Group Usa Inc GV1588 Duct Connector 4 in

Product Description

The IMPERIAL MFG GROUP USA INC GV1588 is a 4-inch round galvanized duct connector designed to join sections of round sheet metal ductwork in forced-air HVAC systems. Both ends are crimped, allowing the connector to slide directly into adjacent duct sections without additional fitting work. The galvanized steel construction resists corrosion in typical residential and light commercial airside environments. HVAC technicians and sheet metal installers use this type of fitting to extend runs, close gaps, or repair existing duct systems. The package includes 6 connectors, making it practical for multi-connection jobs or repeat service calls.

This connector is suited for use in residential and light commercial forced-air heating and cooling duct systems where 4-inch round ductwork is specified. Common applications include branch runs from plenums, bathroom exhaust connections, and dryer vent or ventilation duct extensions where a 4-inch diameter round fitting is required. The crimped-both-ends design simplifies insertion into existing duct sections without sheet metal tools on-site.

Key Features

• 4-inch diameter round profile fits standard 4-inch round ductwork
• Crimped on both ends for tool-free insertion into adjoining duct sections
• Galvanized steel construction for corrosion resistance in airside applications
• Sold in a package of 6 connectors for multi-point installations

Compatibility

Designed as a standard OEM-style replacement and new-installation fitting for 4-inch round galvanized ductwork systems in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal installer. Power down the air handler or furnace before accessing the duct system. Secure the connector with sheet metal screws and seal all joints with UL 181-rated foil tape or duct mastic per local mechanical code requirements. Do not use cloth-backed duct tape as a primary sealant.
