Southwark Metal SP90-26GA_8IN Spiral Duct Elbow 26 Gauge

Product Description

The SOUTHWARK METAL SP90-26GA_8IN is a spiral duct elbow fabricated from hot dip galvanized steel at 26 gauge material thickness. It provides a directional change in round spiral duct systems and is designed to maintain consistent airflow through the transition. The 8-inch inlet and 8-inch outlet dimensions make this a straight-size elbow suited for residential and light commercial HVAC ductwork. HVAC installers and sheet metal mechanics work with this fitting as part of supply or return air distribution systems where spiral pipe is the specified duct type.

This elbow fits into spiral duct installations where ACCA and SMACNA standards govern the design and construction of the air distribution system. It is appropriate for use in forced-air heating and cooling applications using round spiral trunk lines or branch runs. The galvanized steel construction holds up in standard conditioned-space and unconditioned-space duct installations such as attics, crawlspaces, and mechanical rooms.

Key Features

• Hot dip galvanized steel construction resists corrosion in typical duct environments
• 26 gauge material thickness meets standard sheet metal duct fabrication requirements
• 8-inch inlet and 8-inch outlet for a same-size directional transition
• Spiral pipe type maintains the structural integrity of spiral duct runs
• Conforms to ACCA and SMACNA applicable standards for duct fittings

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 8-inch round spiral duct systems built to ACCA and SMACNA standards in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation of spiral duct elbows is performed by licensed HVAC technicians or qualified sheet metal mechanics. The duct system should be de-energized and the air handler shut down before modifying any duct section. Connections are typically secured with sheet metal screws and sealed with UL 181-rated mastic or foil tape per SMACNA guidelines. Follow local mechanical codes and the project duct design for proper fitting orientation and support spacing.
