Southwark Metal 124-NC_7IN Oval to Round Pipe Boot 7 Inch

Product Description

The SOUTHWARK METAL 124-NC_7IN is a no-crimp, oval-to-round sheet metal pipe boot designed for transitioning ductwork from an oval profile to a round 7-inch diameter pipe at a 90-degree elbow. Fabricated from hot dip galvanized steel, this fitting delivers corrosion resistance suited to residential and light commercial HVAC duct systems. The no-crimp end eliminates the need for a separate crimping step during installation, allowing a direct slip connection to standard round duct. HVAC sheet metal installers and duct fabricators use this boot where supply or return air duct must change cross-section geometry while making a directional turn.

This pipe boot is used in forced-air heating and cooling systems where space constraints or layout requirements call for an oval-to-round transition at a 90-degree angle. Typical applications include connecting oval trunk duct to round branch takeoffs, fitting ductwork through wall or floor framing cavities, and completing duct system layouts that follow ACCA and SMACNA standards for residential or light commercial installations. The 7-inch by 7-inch sizing fits standard round pipe of 7-inch diameter.

Key Features

• Oval-to-round geometry handles duct profile transitions in a single fitting
• 90-degree elbow configuration redirects airflow without additional fittings
• No-crimp design allows direct slip connection to round duct, reducing install steps
• Hot dip galvanized steel construction provides corrosion resistance for long service life
• Meets ACCA and SMACNA applicable standards for sheet metal duct fabrication

Compatibility

Designed as an OEM-style sheet metal fitting for use with standard 7-inch round duct pipe in forced-air HVAC systems built to ACCA and SMACNA duct construction standards.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal installer familiar with SMACNA duct construction guidelines. Shut down the air handling unit and isolate the duct system before modifying or connecting duct sections. Secure all joints with sheet metal screws and seal with UL 181-rated tape or mastic as required by local mechanical code. Inspect the galvanized surface for any damage before installation to ensure long-term corrosion resistance.
