Imperial Mfg Group Usa Inc GV1415 4in to 3in Duct Reducer

Product Description

The IMPERIAL MFG GROUP USA INC GV1415 is a 4-inch to 3-inch round pipe reducer designed for galvanized duct systems in HVAC installations. Fabricated from 24-gauge galvanized steel, this reducer transitions airflow from a 4-inch round pipe down to a 3-inch round pipe while maintaining a sealed, secure connection. The small end is crimped to allow easy insertion into a pipe or fitting of the same diameter. HVAC installers and sheet metal technicians use this reducer when adjusting duct branch sizes during trunk-and-branch or radial duct system builds. It is sold in a package of 10 units.

This reducer is suited for residential and light commercial heating, ventilation, and air conditioning ductwork. It performs well in forced-air furnace supply and return runs, exhaust venting, and general round duct transitions where a diameter reduction from 4 inches to 3 inches is required. The galvanized steel construction resists corrosion in typical conditioned-air and venting environments. Licensed HVAC contractors and sheet metal mechanics are the typical installers for this type of fitting.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal mechanics. Shut down and de-energize the air handling unit or furnace before working on connected ductwork. Secure the reducer with sheet metal screws and seal all joints with UL-listed duct tape or mastic sealant per applicable mechanical codes. Follow local mechanical codes and SMACNA guidelines for duct joint fastening and sealing requirements.
