Southwark Metal 106-NC_6IN Pipe End Boot 6x6 No Crimp

Product Description

The SOUTHWARK METAL 106-NC_6IN is a sheet metal pipe end boot designed to transition ductwork from an oval profile to a round opening in forced-air HVAC systems. Fabricated from hot dip galvanized steel, this fitting delivers corrosion resistance suitable for both supply and return air applications. The reverse, no-crimp design allows the boot to slip over adjoining duct sections without a crimped male end, simplifying field assembly. Sized at 6 inches by 6 inches diameter, it meets ACCA and SMACNA standards and is typically installed by licensed sheet metal workers or HVAC technicians during new construction or duct retrofit work.

This boot is used in residential and light commercial forced-air HVAC installations where an oval duct run must terminate or connect to a round collar. The oval-to-round transition is common at air handler connections, register boxes, and branch takeoffs. The no-crimp, reverse configuration is particularly useful when connecting to a fitting that already carries a male crimp, keeping the assembly tight and aligned without additional field modification.

Key Features

• Oval to round transition with reverse, no-crimp slip fit for straightforward field assembly
• Hot dip galvanized steel construction for corrosion resistance in air distribution applications
• 6-inch by 6-inch diameter sizing for consistent airflow alignment at termination points
• Meets ACCA and SMACNA applicable standards for sheet metal duct fabrication
• Rigid sheet metal construction maintains shape under duct pressure and supports duct tape or mastic sealing

Compatibility

Designed as an OEM-style sheet metal fitting for residential and light commercial forced-air duct systems requiring an oval-to-round pipe end boot transition at a 6-inch by 6-inch diameter connection point.

Installation Notes

Installation is performed by licensed HVAC technicians or sheet metal workers following SMACNA duct construction standards. Power down the air handling unit and verify the system is de-energized before working inside the duct system. Seal all joints with UL-listed mastic or foil-backed tape per local mechanical code requirements. Do not over-force the slip fit connection, as distorting the fitting can compromise the seal and airflow performance.
