DuraVent DuraLiner Oval to Round Heavy Duty Flex Pipe: thicker steel for tight chimney openings
The DuraVent DuraLiner Oval to Round Heavy Duty Flex Pipe is a short stainless steel section that bends through a tight chimney opening. Its four layers of thicker steel make it the heavier version of this shape changing part. The bottom is oval to fit an oval stove outlet or a narrow damper opening, where the chimney’s airflow flap sits. The top joins round rigid liner pipe. DuraLiner is DuraVent’s factory insulated double wall pipe for relining a masonry chimney that vents a wood, pellet, coal, oil, or gas appliance.
This part comes in a 6 inch size. Choose a length of 36 or 60 inches on this page. The oval shape carries the same flow as round pipe through a narrower space. Choose the liner shape to suit the chimney’s inside shape. Any portion of this flex above the first clay flue tile needs the DuraLiner Insulation Kit wrapped around it. Looking for the lighter single layer version in 6 or 8 inch? See the DuraVent DuraLiner Oval to Round Flex Pipe.
