Southwark Metal 127-NC_6IN Oval to Round Pipe Boot 6x6

Product Description

The SOUTHWARK METAL 127-NC_6IN is a straight, oval-to-round sheet metal pipe boot designed for duct transitions in HVAC and forced-air ventilation systems. Constructed from hot-dip galvanized steel, this no-crimp boot provides a clean, interference-free connection between an oval duct section and a round collar or pipe. The no-crimp design simplifies installation by eliminating the need to expand or compress the end of the fitting before seating it against adjacent ductwork. It is sized at 6 inches by 6 inches in diameter and is suited for residential and light commercial sheet metal duct assemblies. HVAC installers and sheet metal mechanics are the primary tradespeople who work with this fitting.

This boot is used in forced-air heating and cooling duct systems where a transition from an oval duct profile to a round pipe connection is required. Common install scenarios include trunk-and-branch duct layouts where oval runs connect into round collars at takeoffs, plenums, or equipment transitions. The straight configuration keeps the airflow path direct without angular offset, making it appropriate for tight chase or wall cavity installations where alignment must be maintained. It conforms to ACCA and SMACNA standards, which are the recognized industry references for sheet metal duct fabrication and installation.

Key Features

• Hot-dip galvanized steel construction for corrosion resistance in conditioned air applications
• No-crimp end eliminates field modification before connection, reducing installation time
• Straight oval-to-round geometry maintains direct airflow path through the transition
• Sized at 6 inches by 6 inches diameter for standard residential duct branch sizing
• Meets ACCA and SMACNA applicable standards for sheet metal ductwork

Compatibility

Designed as an OEM-style sheet metal fitting for use in residential and light commercial forced-air duct systems requiring an oval-to-round straight transition at 6 inches by 6 inches diameter.

Installation Notes

Installation is typically performed by licensed HVAC technicians or journeyman sheet metal mechanics. The air handling system or furnace should be powered off and the supply fan confirmed stopped before working on supply or return ductwork. Joints should be sealed with mastic sealant or listed foil tape per SMACNA and local mechanical code requirements. Sheet metal screws are commonly used to secure the boot to adjacent fittings prior to sealing.
