The SOUTHWARK METAL OVP113_7IN is a hot-dip galvanized steel oval sheet metal pipe measuring 7 inches in diameter and 113 inches in length. Designed for low-pressure air distribution systems, this oval duct section is used in residential and light commercial HVAC installations where space constraints make round duct impractical. The hot-dip galvanized finish provides corrosion resistance suited to both conditioned and unconditioned spaces. Licensed HVAC installers and sheet metal contractors use this product as a primary duct section in supply and return air trunk systems built to SMACNA and ACCA standards.
This oval pipe is well suited for residential forced-air heating and cooling systems as well as light commercial air handling applications. Its oval cross-section allows installation in tight floor joist bays, wall cavities, and above-ceiling spaces where round pipe does not fit. At 113 inches in length, a single section spans most standard stud and joist bay runs, reducing the number of joints required in a trunk line assembly.
Designed as an OEM-style replacement or new-installation component for residential and light commercial HVAC duct systems using 7-inch oval duct configurations.
Installation should be performed by a licensed HVAC technician or sheet metal contractor familiar with SMACNA duct construction standards. Power down the air handling unit before making any connections to an existing duct system. Secure all joints with approved sheet metal screws and seal with UL 181-rated mastic or foil tape to meet applicable building and energy codes. Support the duct section at intervals consistent with SMACNA hanger and support guidelines for the installation environment.
