DuraVent DuraLiner Round to Round Heavy Duty Flex Pipe: thicker steel for a tight chimney bend
The DuraVent DuraLiner Round to Round Heavy Duty Flex Pipe is a short flexible section for the bend above a fireplace. Four layers of thicker stainless steel make it tougher than the single layer version when pushed, twisted, or scraped past a tight opening. It passes the smoke shelf, the ledge above the fireplace, and the old damper opening after the damper is removed. Both ends are round, with fittings already attached for rivet connections. DuraLiner is DuraVent’s factory insulated double wall pipe for relining a masonry chimney that vents a wood, pellet, coal, oil, or gas appliance.
Choose a 6 or 8 inch diameter, then a length of 36 or 60 inches. This section joins round DuraLiner parts at the bend, rather than lining the full chimney. Any flex extending above the first clay flue tile needs the DuraLiner Insulation Kit. DuraVent recommends insulating every flex section to help exhaust move up the chimney and for safety. Have an easier bend? The lower priced DuraVent DuraLiner Round to Round Flex Pipe uses a single layer of steel.
