Southwark Metal SC10 Spiral Coupling 10 Inches

Product Description

The SOUTHWARK METAL SC10 is a 10-inch spiral coupling designed for connecting sections of spiral round ductwork in forced-air HVAC distribution systems. This fitting creates a secure, low-leakage joint between spiral duct runs, maintaining airflow integrity through the connection point. It is a standard component in commercial and residential sheet metal duct systems and is typically installed by licensed sheet metal workers or HVAC installers during new construction or duct modification work.

The SC10 is sized for 10-inch spiral round duct, making it appropriate for medium to large residential trunk lines and commercial branch runs where consistent airflow and duct integrity are required. It is used wherever two sections of 10-inch spiral duct must be joined in a straight run without a fitting transition.

Key Features

• 10-inch diameter sizing matches standard spiral round duct dimensions
• Designed for straight-run connections between spiral duct sections
• Supports low-leakage duct assembly when sealed per code
• Compatible with standard spiral round duct commonly used in commercial and residential HVAC systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 10-inch spiral round duct systems used in commercial and residential forced-air HVAC applications.

Installation Notes

Installation is typically performed by licensed sheet metal workers or HVAC technicians. The system should be depressurized and the air handling unit powered down before working on duct sections. All joints should be sealed with UL 181-listed mastic or foil tape per SMACNA standards and applicable mechanical codes. Secure the coupling to each duct section with sheet metal screws at even intervals before applying sealant.
