This 6-inch 316 grade flue liner is constructed from two individual strips of 316 stainless steel. It also has a 15-year guarantee compared to the 10 years that most other liners offer.

Most other liners are made from one strip of steel which is folded to create the inner and outer layer. This folding weakens the steel. As Dura Flue is made from two strips of steel this weakening doesn't happen meaning it's a strong more reliable flexible flue liner.

The minimum length you can order online is 5 metres.
