The IMPERIAL MFG GROUP USA INC GV0381 is a 30-gauge galvanized steel furnace pipe section measuring 6 inches in diameter and 24 inches in length. This round duct pipe is used in low-pressure residential and light commercial warm-air heating systems to connect furnace outlets to vent runs and branch takeoffs. The galvanized steel construction resists corrosion and holds its shape under the thermal cycling typical of forced-air heating applications. Licensed HVAC technicians and sheet metal installers work with this type of pipe during new installations, system modifications, and ductwork repairs.
This pipe section is suited for use in residential gas and oil furnace ductwork systems where a 6-inch round duct run is required. It fits standard 6-inch round duct fittings, elbows, collars, and connectors used in conventional forced-air distribution systems. The 24-inch length makes it practical for short straight runs, transitions, and connections between fittings. It is sold in a package quantity of 10 sections, making it well suited for contractors stocking material for a full installation or service job.
Designed as an OEM-style replacement and standard-fit component for residential and light commercial forced-air furnace ductwork systems using 6-inch round duct configurations.
Installation is typically performed by a licensed HVAC technician or sheet metal installer. Shut down and de-energize the furnace system before working on any connected ductwork. Secure pipe joints with sheet metal screws and seal with listed duct sealant or foil tape in accordance with local mechanical codes and SMACNA guidelines. Avoid over-crimping the pipe ends, as deformation can restrict airflow and compromise fitting connections.
