DuraVent DuraLiner Round to Round Flex Pipe: a flexible bend with round connections at both ends
The DuraVent DuraLiner Round to Round Flex Pipe is a short flexible stainless steel section for the bend inside an old masonry chimney. It passes the smoke shelf, the ledge above the fireplace, and the opening left when the old damper is removed. Both ends are round, joining round rigid liner above to a round connector below. Its single layer of steel lets it bend by hand. 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 flexible piece is for the bend, not the full chimney run. Any portion extending above the first flue tile, where the chimney’s clay lining begins, must be wrapped with the DuraLiner Insulation Kit. DuraVent recommends insulating every flex section to help draft and safety. Need thicker steel? See the DuraVent DuraLiner Round to Round Heavy Duty Flex Pipe.
