Imperial Mfg Group Usa Inc BM0037 Oval Round Duct Adapter 6 in

Product Description

The IMPERIAL MFG GROUP USA INC BM0037 is a 6-inch, 24-gauge black steel oval-to-round duct adapter used in forced-air HVAC systems to transition between oval and round duct sections. This fitting connects oval ductwork runs to round collars on air handlers, furnaces, plenums, or duct fittings where space constraints or existing duct layouts require a profile change. The 24-gauge construction provides adequate rigidity for residential and light commercial applications. HVAC installers and sheet metal mechanics use this adapter during new construction, renovation, or service work where duct configurations require a geometry transition.

This adapter is suited for residential forced-air systems where oval duct is routed through floor joists, wall cavities, or other tight spaces before connecting to a round collar. It is commonly installed in supply or return trunk transitions and is appropriate for standard low-pressure HVAC duct systems. The black finish is typical for exposed or semi-exposed installations where appearance is a consideration. It is sold in a package quantity of 12 units, making it practical for contractors stocking fittings for multiple jobs.

Key Features

• 6-inch nominal size transitions oval duct profile to round collar
• 24-gauge steel construction provides consistent shape retention in low-pressure duct runs
• Black finish suitable for visible or semi-exposed duct installations
• Sold in a package of 12 units for contractor convenience
• Compatible with standard round duct collars at the 6-inch diameter

Compatibility

Designed as an OEM-style replacement and new-installation fitting for residential and light commercial forced-air duct systems requiring a 6-inch oval-to-round transition.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal mechanics. Shut down the air handling system and de-energize the air handler or furnace before modifying ductwork. Secure the adapter with sheet metal screws and seal all joints with UL-listed foil tape or mastic sealant in accordance with local mechanical codes and SMACNA guidelines. Do not use this fitting in high-pressure or high-velocity commercial duct systems unless verified for the application.
