Imperial Mfg Group Usa Inc GV1417 Taper Reducer 6x4 in

Product Description

The IMPERIAL MFG GROUP USA INC GV1417 is a 24-gauge galvanized steel taper reducer designed to transition ductwork from a 6-inch diameter down to a 4-inch diameter. The small end arrives pre-crimped for a faster, tool-free connection to the next duct section or fitting. HVAC installers and sheet metal contractors use this fitting in residential and light commercial forced-air distribution systems to step down trunk or branch duct sizes while maintaining airflow efficiency. The galvanized steel construction resists corrosion in typical attic, crawlspace, and mechanical room environments.

This taper reducer is suited for residential and light commercial HVAC duct installations where a smooth, concentric diameter transition is needed between a 6-inch and 4-inch round duct run. It is commonly installed when reducing branch takeoffs from a main trunk line or transitioning from a larger collar to a smaller flex or rigid duct run. The pre-crimped small end simplifies connections to standard duct fittings without additional field fabrication. It is sold in a package of 12 units, making it practical for contractors stocking hardware for multi-room or multi-unit projects.

Key Features

• 24-gauge galvanized steel construction provides corrosion resistance for long-term duct system performance
• Tapered concentric design transitions airflow from 6 inches to 4 inches with minimal turbulence
• Small end is factory-crimped for direct insertion into mating duct sections or fittings
• Sold in a package of 12 units to support multi-run or multi-unit installations
• Compatible with standard round galvanized duct and fittings in forced-air distribution systems

Compatibility

Designed as an OEM-style replacement and new-installation fitting for standard 6-inch to 4-inch round galvanized ductwork in residential and light commercial forced-air HVAC systems.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal contractors following local mechanical codes and SMACNA duct construction standards. Power down the air handling unit before connecting or modifying any duct section. Secure the fitting with sheet metal screws and seal all joints with listed duct tape or mastic sealant per applicable mechanical code requirements. Do not use this fitting in applications requiring higher-gauge material or pressure ratings beyond standard residential forced-air systems.
