Imperial Mfg Group Usa Inc GV0798 Taper Reducer 10x8 26GA

Product Description

The IMPERIAL MFG GROUP USA INC GV0798 is a galvanized steel taper reducer and increaser designed for round duct transitions in forced-air HVAC systems. Built from 26-gauge galvanized steel, this fitting transitions a 10-inch duct diameter down to an 8-inch connection without a crimped end, allowing for a clean slip-fit or drive-cleat installation on either end. HVAC installers and sheet metal mechanics use this type of fitting to balance airflow between main trunk lines and branch runs or to adapt equipment collars to existing ductwork. The no-crimp design accommodates a wider range of connection methods in the field.

This reducer and increaser is suited for residential and light commercial forced-air duct systems where a concentric round transition between a 10-inch and 8-inch diameter is required. Typical applications include connecting supply air handlers, inline fans, or box equipment to existing duct runs of differing diameters. The galvanized finish provides corrosion resistance appropriate for conditioned-space and attic duct installations. This product is sold in a package quantity of 10 pieces per unit of measure.

Compatibility

Designed as an OEM-style replacement and standard-fit component for round duct systems requiring a concentric transition between 10-inch and 8-inch diameter sections.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal mechanics following applicable mechanical codes. Power down and lock out the air handling unit before making duct connections. Secure connections with approved sheet metal screws and seal all joints with listed duct sealant or metal-backed tape per local mechanical code requirements. Do not use this fitting in applications outside its rated gauge and diameter specification.
