Southwark Metal SPCON-26GA_10IN Spiral Pipe Coupling 26GA 10IN

Product Description

The SOUTHWARK METAL SPCON-26GA_10IN is a 10-inch spiral pipe connector coupling fabricated from hot dip galvanized steel at 26 gauge thickness. It is designed to join sections of spiral round duct in low-pressure HVAC supply and return air distribution systems. The galvanized finish provides corrosion resistance suited to both indoor mechanical rooms and unconditioned spaces such as attics and crawlspaces. HVAC installers and sheet metal contractors use this fitting to maintain a continuous, sealed duct run. Compliance with ACCA and SMACNA standards means the fitting meets the dimensional and performance benchmarks required on commercial and residential mechanical projects.

This coupling is used in residential and light commercial HVAC ductwork installations where spiral round pipe is the primary distribution method. It connects two lengths of spiral duct at the same nominal diameter, maintaining consistent airflow cross-section through the run. Typical applications include supply trunk extensions, branch take-off connections, and duct repairs requiring a slip-fit mechanical joint. Sheet metal contractors and HVAC technicians install this fitting during new construction rough-in or service replacement work.

Key Features

• Hot dip galvanized steel construction for corrosion resistance in conditioned and unconditioned spaces
• 26 gauge material thickness consistent with standard spiral duct fabrication practice
• 10-inch nominal diameter matches standard spiral pipe sizing for direct slip-fit connection
• Manufactured to ACCA and SMACNA applicable standards for dimensional accuracy and system integrity
• Designed for low-pressure round duct systems in HVAC air distribution applications

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 10-inch nominal spiral round duct systems meeting ACCA and SMACNA standards in residential and light commercial HVAC applications.

Installation Notes

Installation is typically performed by licensed sheet metal contractors or HVAC technicians following SMACNA duct construction standards. Power down the air handling unit and close the supply air isolation before working in the duct system. Secure the coupling with sheet metal screws at the overlapping joint and seal all longitudinal and circumferential seams with UL 181-listed mastic or foil tape per local mechanical code requirements. Do not use this fitting in high-pressure or high-velocity duct systems unless the system design and gauge selection have been verified against SMACNA pressure class tables.
