The IMPERIAL MFG GROUP USA INC GV0380 is a 26-gauge galvanized steel furnace pipe section measuring 6 inches in diameter by 24 inches in length. This straight pipe section is a core component in low-pressure residential and light commercial heating duct and venting assemblies. The galvanized coating provides corrosion resistance for long service life in indoor heating applications. HVAC installers and sheet metal contractors use this pipe when fabricating or extending round flue and supply duct runs connected to gas or oil furnace systems.
This pipe section is suited for residential furnace installations where 6-inch round galvanized pipe is specified. It fits into standard round duct assemblies, connects to compatible elbows, tees, and collars of the same diameter, and is commonly used in basement, crawl space, and utility room heating system roughins. The 24-inch length makes it a practical straight run for transitioning between furnace outlets and larger trunk lines or flue connections. Sold in a package of 10 units, it is well suited for contractors completing multi-unit or full-system installations.
Designed as an OEM-style replacement and new-installation component compatible with standard 6-inch round galvanized furnace pipe systems using 26-gauge fittings, elbows, and collars.
This pipe is typically installed by licensed HVAC technicians or sheet metal contractors following local mechanical codes and IFGC guidelines. Always shut down the furnace and allow the system to cool completely before disconnecting or extending any duct or flue pipe sections. Secure joints with sheet metal screws and seal with approved HVAC tape or mastic as required by local code. Do not use galvanized pipe in high-temperature positive-pressure flue applications without verifying the rating is appropriate for the specific venting category.
