DuraVent 5 Inch Diameter Aluminum DuraFlex Chimney Liner Kit

Give your chimney a fresh start with the DuraVent 5 Inch Diameter Aluminum DuraFlex Chimney Liner Kit. Made from aluminum, this flexible liner is designed for relining masonry chimneys, so it can be fed right into the flue where a reline is needed. It's listed for Type B gas vent use and works with Category I draft hood-equipped appliances, which gives you a versatile option for your setup. The liner helps protect your masonry chimney from flue condensation, keeping the passage in better shape over time. Each kit includes the length, cap, top plate, and mortar sleeve you need to get started, so you have the core pieces in one box.
