DuraVent DuraLiner 6" Oval-To-Round Heavy Duty Stainless Steel Flex Pipe
The DuraVent DuraLiner 6" Oval-To-Round Heavy Duty Stainless Steel Flex Pipe is a premium chimney liner engineered to deliver safe, efficient venting for wood-burning stoves, fireplace inserts, and high-heat heating appliances. As part of the advanced DuraLiner chimney liner system, this heavy-duty flex pipe provides a secure transition from an oval appliance outlet to a round chimney liner while protecting masonry chimneys from damaging flue gases. Its rugged stainless steel construction makes it ideal for demanding chimney relining and fireplace insert installations.
Built with DuraVent’s innovative factory-insulated technology, this 6-inch oval-to-round stainless steel flex pipe eliminates the need for field-wrapped insulation, additional spacers, or extensive preparation during installation. The smooth inner wall helps minimize creosote buildup, promoting improved airflow, better draft, and easier maintenance. Designed for zero/zero clearance high-heat wood-burning applications, DuraLiner reduces installation labor by 50% or more while delivering dependable, code-compliant performance. Approved for use in both the USA and Canada, it offers lasting durability and reliable chimney protection.
