A flue liner kit 316 Grade or 904 Grade?

In short, if you are just burning seasoned wood then you should buy the 316-grade flue liner kit. If you are burning a mix of seasoned wood and smokeless coal, or smokeless coal on its own, then the 904 flue liner kit  will be a better choice. 


These flue liner kits provide everything you need to fit and connect your liner.

The flue liner kit includes the nose cone, flexible flue liner, flue adaptor to connect the flexible flue liner to the stove pipe and a pot hanger rain cap. The rain cap acts as bird guard, cowl and supports the liner from chimney pot.


You'll require a 6 inch flue liner if you wish to burn coal, you can use a 5 inch liner with a Defra Approved Wood Burning Stove.

Quality flue liner kit

Lining a chimney can be a costly and time-consuming exercise and something that you do not want to repeat because of a liner failing. Therefore, we do not sell cheap inferior flue liners, and only offer our customers the best liner on the market, but still at a fantastic price. Duraflue is designed for professional trade-fitters desiring a premium product for chimney lining.

Duraflue chimney liner is created from TWO compressed stainless-steel layers. This unique laminate stays smooth when the product is passed around chimney bends (with a lesser-quality liner the laminate usually comes apart when dragged through bends - allowing acids from soot deposits to enter and later cause corrosion).
